Question

A woman is walking at the rate of 90 yards per minute. How fast is she going in feet per second?

Answer 1

She is going at the rate of 4.5 feet per second.

Explanation:

Given:

The rate of walking is 90 yards per minute.

Now, to find the rate in feet per second.

1 yard = 3 foot.

1 minute = 60 seconds.

So, first we find the rate of walking per second in yard =
`90/ 60`

Therefore by dividing we get =
`1.5 yard`

Now, we find the rate of walking per second in feet =
`1.5* 3`

So, by multiplying we get =
`4.5 feet`

Therefore, she is going at the rate of 4.5 feet per second.
