Question

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

Answer 1

Answer:

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

Step-by-step 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 = $90\div 60$

Therefore by dividing we get = $1.5 yard$

Now, we find the rate of walking per second in feet = $1.5\times 3$

So, by multiplying we get = $4.5 feet$

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