A swimmer is capable of swimming at 1.4m/s in still water. a. How far downstream will he land if he swims directly across a 180m wide river? b. How long will it take him to reach the other side.

Explanation:

From the given information:

a) the distance(D) showing how dar downstream he will land can be computed as follows:

Assuming the current of the river = 0.2 m/s

D = 36 m ÷ 1.4

D = 25.71 m

The required time (t) to reach the other side is:

time (t) = 180 m/ 1.4 m/s

time (t) = 128.57 seconds
