You can put this solution on YOUR website! Assume the distance to Austin is d miles.
d*(1/70 + 1/50) = 36/5
d = (36/5)*(50*70/120) = 210 miles

-----------
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
