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
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=
