Question

A person is walking at a rate of 9 feet every 4 seconds.

(a) Find their speed, i.e. the rate the distance

Answer 1

v = 2.25 ft/s

Explanation:

Given that,

A person is walking at a rate of 9 feet every 4 seconds.

We need to find their speed. We know that, the speed of total distance divided by time taken. So,

`v=(d)/(t)\\\\v=(9\ ft)/(4\ s)\\\\v=2.25\ ft/s`

So, the speed is 2.25 ft/s.
