Arunner runs 4875 ft in 6.85 minutes. what is the runners average speed in miles per hour?

Answer:

Speed of the runner is 8.08 miles per hour approximately.

Explanation:

Given:

A runner runs =4875 ft

Time Taken = 6.85 minutes.

To Find:  

Average speed of the runner in miles per hour=?

Solution:

Distance = Speed x time

Conveting feet into miles:

=>Distance= miles

=>Distance = 0.9232955 miles

Converting minutes into hours:

time = 6.85 minutes

=>  hours

=> = 0.1141667 hours.

Now, we know that, distance = speed x time  

Then, 0.9232955 miles = speed x 0.1141667 hours  

=>speed =

=>speed = 8.08725749

newton's first law of motion
