Question 740115
eric averaged 50 MPH traveling from denevr to minneapolis. Returning by a different route that covered the same number of miles, he averaged 55 mph. what is his distance between the two cities if hid total travel time was 32 hrs? 
------------
Avg speed for the round trip = 2*50*55/(50+55) = 5500/105
= 1100/21 mi/hr
-----------
RT distance = (1100/21)*32
One way = 17600/21 miles
=~ 838.1 miles
