Question

A baseball pitcher pitches a ball at the speed of 83 mph what conversion factors can be used to find the speed of the ball in feet per second

Answer 1

You would want to convert miles per hour into feet per hour, then you should turn feet per hour into feet per second. Alternatively, you could turn miles per hour into miles per second, and then turn miles per second into feet per second

Answer 2

Answer: $121.73\text{ feet per second}$

Step-by-step explanation:

Given : The speed of a  baseball pitcher  = 83 mph

or  83 miles per hour

Since , we know that

1 mile= 5280 feet

1 hour = 3600 seconds

Then,  83 miles per hour = $\dfrac{\text{83 mile}}{\text{1 second}}=\dfrac{83\times5280\text{ feet}}{1\times3600\text{ seconds}}$

$\approx121.73\text{ feet per second}$

Hence, the speed of the ball in feet per second = $121.73\text{ feet per second}$
