Question

Your playing base ball with your dad. You toss the ball and it takes 14 seconds for the ball to reach your dad. Your dad is 100 meters away from you. How many miler per hour did the ball fly?

Answer 1

The formula to calculate the speed of the ball is given to be:

`s=(d)/(t)`

where s is the speed, d is the distance, and t is the time.

From the question, we have:

`\begin{gathered} d=100\text{ meters} \\ t=14\text{ seconds} \end{gathered}`

Therefore, the speed is calculated to be:

`s=(100)/(14)=7.14\text{ meters per second}`

To convert from meters per second to miles per hour, we multiply the value by 2.237.

Therefore, the speed will be:

`\begin{gathered} s=7.14*2.237 \\ s=15.97 \end{gathered}`

The speed is 15.97 miles per hour.
