FAQs

How do you find the length of a class when the start and end times are given?

Compute the difference between the end time and the start time, converting hours and minutes as needed to get the elapsed duration.

What do you do if the problem asks for a start time instead of a duration?

Subtract the given elapsed time from the end time to determine the start time.

How is the rowing race challenge solved when there are multiple legs and breaks?

Add the total time for all legs and the breaks between legs (no break after the last leg), then add that total to the race start time to get the finish time.
