Answer:

36.67 feet / second

Explanation:

We will be using Dimensional Analysis to solve this question

We are given the rate: 25 miles / hour

Converting the Miles to feet:

We know that 1 mile = 5280 feet

So, we can say that
(5280 feet)/(1 mile) = 1

Multiplying the Given rate by 1:


(25 miles)/(Hour) * 1

(multiplying by 1 will not change the actual value of the expression)


(25 miles)/(Hour) *
(5280 feet)/(1 mile) (since 5280 feet/ 1 mile = 1)

here, the 'mile' will cancel out and we will get:


(25 * 5280 feet )/(Hour )


(132000 feet)/(Hour)

Converting the Hours to Seconds:

We know that 1 hour = 3600 seconds

So, we can say that:


(1 Hour)/(3600 seconds) = 1

Multiplying the Rate by 1:


(132000 feet)/(1 Hour) * 1

(multiplying by 1 will not change the actual value of the expression)


(132000 feet)/(1 Hour) * (1 Hour)/(3600 seconds) (since 1 hour / 3600 seconds = 1)

Here, the 'Hour' in the numerator and the denominator will cancel out to make:


(132000 feet)/(3600 seconds)

which can be simplified to:


(36.67 feet)/(second)

Therefore, 25 mph can also be written as 36.67 feet per second
