Ivan drove to the mountains last weekend. there was heavy traffic on the way there, and the trip took 7 hours. when ivan drove home, there was no traffic and the trip only took 4 hours. if his average rate was 27 miles per hour faster on the trip home, how far away does ivan live from the mountains? do not do any rounding.

252 miles

Explanation:

Given

During his way to mountain it took 7 hr to drive

and during his return trip it took 4 hr to return

Let x be the distance between home and mountain

average speed for return is  27 miles per hour faster than his former trip

let v be the speed on his way to mountain thus v+27 is his return speed

thus ----1

for return trip

-----2

divide  1 & 2

thus

c) power lifting, will be your answer.
