Cole drove from home to work at an average speed of 50 kmh. He then returned home at an average speed of 110 kmh. If the round trip took a total of 2 hours, how many minutes did it take Cole to drive to work? Choose the most appropriate option:
A) 66.5
B) 70.5
C) 72.5
D) 75.5
E) 82.5

Rationale: "let the distance one way be x time from home to work = x / 50 time from work to home = x / 110 total time = 2 hrs ( x / 50 ) + ( x / 110 ) = 2 solving for x , we get x = 275 / 4 time from home to work in minutes = ( 275 / 4 ) * 60 / 50 = 82.5 minutes ans = e"
Answer: E
