Question

“The distance from a pitcher's mound to home plate is 60' 6". The opposing team's ace reliever can throw his fastball at a speed of 100 MPH. To the nearest thousandth ofa second, now long will it take the ball to get to the plate?” please help me out!!!

Answer 1

To determine the time, we will use the following formula:

`S=(d)/(t),`

where S is speed, d is distance, and t is time.

Before substituting, we convert from feet inches to miles:

`60^(\prime)6`

Substituting the above value, and S=100 MPH, we get:

`100MPH=(60.5)/(5280t),`

solving for t, we get:

`t=(60.5)/(5280*100)=(11)/(69000)hours.`

Finally, recall that:

`1\text{ hour=3600 seconds,}`

therefore:

`t=0.413\text{ seconds.}`

Answer:

`0.413\text{ seconds.}`
