Question

A river 500 ft wide flows with a speed of 6 ft/s with respect to the earth. A woman swims with a speed of 3 ft/s with respect to the water. a) If the woman heads directly across the river, how far downstream is she swept when she reaches the opposite bank

Answer 1

The distance traveled in this time downstream is 1,000 ft

Explanation:

In order to calculate how far downstream is she swept when she reaches the opposite bank we would have to make the following calculation:

distance traveled in this time downstream=speed*time to reach other side

speed=6 ft/s

time to reach other side=500/3

time to reach other side=166.66 s

Therefore, distance traveled in this time downstream = 6*166.66

distance traveled in this time downstream= 1,000 ft

The distance traveled in this time downstream is 1,000 ft
