Question

Andy is kayaking on a river in Morgan County, moving down the river at a speed of 10 miles per hour. Meanwhile, Tatsu is on a jet ski 11 miles away, moving up the river at 20 miles per hour. How long will it be before the two meet? (answer in how many hours and minutes)

Answer 1

The answer is 22 minutes:

20x for Tatsu and 10x for Andy

30x = 11

x = 11/30

11/30 * 60 = 22
