Question

A rhino can run at speeds of about 28 miles per hour. What is that speed in feet per second, to the nearest whole number?

Answer 1

28 mph is approximately 41.0666... fps.

This is because 1mph is approximately 1.4666... fps.

Answer 2

The speed of a rhino is 41 feet/second.

Explanation:

A rhino can run at speed of about 28 miles per hour.

In one hour a rhino can run = 28 miles

As we know 1 hour = 3600 seconds

1 mile = 5280 feet

28 miles = 5280 × 28 = 147,840 feet

Therefore, we can say in 3600 seconds a rhino can run = 147,840 miles

So the speed per second =
`(147840)/(3600)` = 41.06 ≈ 41 feet

The speed of a rhino is 41 feet/second.
