Question

Convert the rate 25 miles per hour to feet per second

Answer 1

Mile Per Hour to Foot Per Second Conversion Table
Miles Per Hour Feet Per Second
22 mph 32.27 ft/s
23 mph 33.73 ft/s
24 mph 35.2 ft/s
25 mph 36.67 ft/s

Answer 2

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
