Question 1185182: This question is pretty simple but i honestly don't understand it.
A runner leaves his house at 7:45 for a morning run. If he travels at an average speed of 6 mph and gets back
home at 10:00, how many miles did he run?
please can someone explain to me in depth how to get my answer and where the numbers are coming from. thank you

You can put this solution on YOUR website! .
To find the distance traveled, multiply the rate (which is 6 miles per hour)
by the travel time (which is 2 hours and 15 minutes, or 2  hours).
By multiplying, we get 6 * 2 = 6 * 2.25 = 13.5 miles. ANSWER
---------------
Solved, answered and explained.
===============
comment from student : how did you get 2:15? i hate to sound stupid by asking but somehow im adding my time wrong because i got 2:55
My response : I spent long time thinking from where and how you got 55 minutes,
and then, finally, got understanding.
In your mind, you think that 1 hour is 100 minutes.
Dear visitor, it is a MISTAKE to think so.
1 hour is not the same as 1 dollar.
It is true that 1 dollar is 100 cents, but 1 hour is not 100 minutes: it is ONLY 60 minutes.
I assume that every elementary school student knows it starting from his (or her) 2-nd grade age.
