Question

A person is training for a cross country and manages to run 2 miles in a time of 12 mins what was the runners average velocity in miles per hour

Answer 1

10 miles per hour

Explanation:

To convert 2 miles / 12 minutes to MILES per HOUR, we need to set up a simple ratio:

*** Let x be the average velocity (in mph) ***

`(Miles)/(Hour)>>>(2Miles)/(12Mins)=(xMiles)/(60Minutes)\\2*60 = 12*x\\120=12x\\x=(120)/(12)=10`

So the average velocity in miles per hour is 10

Answer 2

10 miles per hour

Explanation:

Average velocity=distance covered/time in hours

Distance=2 miles

time=12minute

change minutes to hour=12/60 =0.2hrs

v=2÷0.2

v=10miles per hour
