Question 988641
a jogger runs a distance at a speed of 8 miles per hour and returns the same distance running at a speed of 6 mph. find the total distance that the jogger ran if the total time running was one hour forty five minutes.
------------
Avg speed of the round trip = 2*8*6/(8+6) = 96/14
= 48/7 mi/hr
------
d = r*t = (48/7)*(7/4)
d = 12 miles
