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

Answer:

36.67 feet / second

Step-by-step 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 $\frac{5280 feet}{1 mile}$ = 1

Multiplying the Given rate by 1:

$\frac{25 miles}{Hour}$ * 1

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

$\frac{25 miles}{Hour}$ * $\frac{5280 feet}{1 mile}$                                                          (since 5280 feet/ 1 mile = 1)

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

$\frac{25 * 5280 feet }{Hour }$  

$\frac{132000 feet}{Hour}$

Converting the Hours to Seconds:

We know that 1 hour = 3600 seconds

So, we can say that:

$\frac{1 Hour}{3600 seconds}$ = 1

Multiplying the Rate by 1:

$\frac{132000 feet}{1 Hour} * 1$

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

$\frac{132000 feet}{1 Hour} * \frac{1 Hour}{3600 seconds}$                                   (since 1 hour / 3600 seconds = 1)

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

$\frac{132000 feet}{3600 seconds}$

which can be simplified to:

$\frac{36.67 feet}{second}$

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