=========================
Do it like this one:
-----------
If you drove to Austin at 70 miles per hour and returned at 50 miles per hour.what is the distance driven to Austin if total driving time was 7.2 hours
-----------
Avg speed for the round trip = 2*70*50/(70+50)
= 7000/120
= 175/3 mi/hr
------------
d = r*t = (175/3)*7.2
d = 420 miles RT
one-way = 210 miles
