Convert the rate 25 miles per hour to feet per second

36.67 feet / second

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 = 1

Multiplying the Given rate by 1:

* 1

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

*                                                          (since 5280 feet/ 1 mile = 1)

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

Converting the Hours to Seconds:

We know that 1 hour = 3600 seconds

So, we can say that:

= 1

Multiplying the Rate by 1:

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

                                  (since 1 hour / 3600 seconds = 1)

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

which can be simplified to:

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