Two steamers leave a port on a river at the same time, one travel east and the other travel west. Each is traveling 22 mph. How long will it take for them to be 100 miles apart?

Answer 1

d = rt

Since the steamers are traveling in opposite directions, the combined rate is:

r = 44 mph

100 = 44t

t = 100/44 ≈ 2.272 hours
