Question

In a river, a trout passed beneath a woman who was swimming at 1,800 centimeters per minute. The trout swam 7,200 centimeters directly upstream at a constant velocity. It swam that distance in 1.6 minutes. What was the trout's velocity?

Write your answer as a whole number.

centimeters per minute upstream

Answer 1

Answer:

4,500 cm per minute

Explanation:

Use the triangle of speed, distance, and time for reference.

You need the speed, so:

$s=\frac{d}{t}=\frac{7200}{96} =75$

We change minutes to seconds to make it a round number

Then we just multiply, 75 times 60, because there are 60 seconds in one minute. We get 4,500 cm/m.
