+# Day 6: Wait For It
+The ferry quickly brings you across Island Island. After asking around, you discover that there is indeed normally a 
+large pile of sand somewhere near here, but you don't see anything besides lots of water and the small island where the 
+ferry has docked.
+
+As you try to figure out what to do next, you notice a poster on a wall near the ferry dock. "Boat races! Open to the 
+public! Grand prize is an all-expenses-paid trip to **Desert Island**!" That must be where the sand comes from! Best of 
+all, the boat races are starting in just a few minutes.
+
+You manage to sign up as a competitor in the boat races just in time. The organizer explains that it's not really a 
+traditional race - instead, you will get a fixed amount of time during which your boat has to travel as far as it can, 
+and you win if your boat goes the farthest.
+
+As part of signing up, you get a sheet of paper (your puzzle input) that lists the **time** allowed for each race and 
+also the best **distance** ever recorded in that race. To guarantee you win the grand prize, you need to make sure you 
+**go farther in each race** than the current record holder.
+
+The organizer brings you over to the area where the boat races are held. The boats are much smaller than you expected - 
+they're actually **toy boats**, each with a big button on top. Holding down the button **charges the boat**, and 
+releasing the button **allows the boat to move**. Boats move faster if their button was held longer, but time spent 
+holding the button counts against the total race time. You can only hold the button at the start of the race, and boats 
+don't move until the button is released.
+
+For example:
+```
+Time:      7  15   30
+Distance:  9  40  200
+```
+This document describes three races:
+* The first race lasts `7` milliseconds. The record distance in this race is `9` millimeters.
+* The second race lasts `15` milliseconds. The record distance in this race is `40` millimeters.
+* The third race lasts `30` milliseconds. The record distance in this race is `200` millimeters.
+
+Your toy boat has a starting speed of **zero millimeters per millisecond**. For each whole millisecond you spend at the 
+beginning of the race holding down the button, the boat's speed increases by **one millimeter per millisecond**.
+
+So, because the first race lasts `7` milliseconds, you only have a few options:
+* Don't hold the button at all (that is, hold it for **`0` milliseconds**) at the start of the race. The boat won't 
+move; it will have traveled **`0` millimeters** by the end of the race.
+* Hold the button for **`1` millisecond** at the start of the race. Then, the boat will travel at a speed of `1` 
+millimeter per millisecond for `6` milliseconds, reaching a total distance traveled of **`6` millimeters**.
+* Hold the button for **`2` milliseconds**, giving the boat a speed of `2` millimeters per millisecond. It will then 
+get `5` milliseconds to move, reaching a total distance of **`10` millimeters**.
+* Hold the button for **`3` milliseconds**. After its remaining `4` milliseconds of travel time, the boat will have 
+gone **`12` millimeters**.
+* Hold the button for **`4` milliseconds**. After its remaining `3` milliseconds of travel time, the boat will have 
+gone **`12` millimeters**.
+* Hold the button for **`5` milliseconds**, causing the boat to travel a total of **`10` millimeters**.
+* Hold the button for **`6` milliseconds**, causing the boat to travel a total of **`6` millimeters**.
+* Hold the button for **`7` milliseconds**. That's the entire duration of the race. You never let go of the button. 
+The boat can't move until you let go of the button. Please make sure you let go of the button so the boat gets to 
+move. **`0` millimeters**.
+
+Since the current record for this race is `9` millimeters, there are actually **`4`** different ways you could win: 
+you could hold the button for `2`, `3`, `4`, or `5` milliseconds at the start of the race.
+
+In the second race, you could hold the button for at least `4` milliseconds and at most `11` milliseconds and beat the 
+record, a total of **`8`** different ways to win.
+
+In the third race, you could hold the button for at least `11` milliseconds and no more than `19` milliseconds and still 
+beat the record, a total of **`9`** ways you could win.
+
+To see how much margin of error you have, determine the **number of ways you can beat the record** in each race; in 
+this example, if you multiply these values together, you get **`288`** (`4` * `8` * `9`).
+
+Determine the number of ways you could beat the record in each race. **What do you get if you multiply these numbers 
+together**?
