it took tammy 6 hrs to get to the mountains due to heavy traffic. it only took her 4 hrs to drive back home from the mountains with no traffic. tammy drove 22 miles per hour faster on the way home than she did driving to the mountains, how many miles away from the mountains does tammy live?

6x   =  4 (x+22)

2x = 88

x = 44  m/hr   for the trip up  at 6 hrs = 264 miles
