Kent swam 150 m up a river that has a steady current in 5 minutes and returned downstream in 3 minutes. How fast would he have swum in still water, and what? is the speed of the current

Answer :

The current of the stream is 1.2 meters per minute.

Explanation:

v = (150 / 5) - x

v = (150 / 3) + x

(150 / 5) - x = (150 / 3) + x

Now, solve for x:
(150 / 5) = (150 / 3) + 2x
(3 / 5) = 2x
x = 6 / 5 = 1.2
