Cole drove from home to work at an average speed of 80 kmh. He then returned home at an average speed of 120 kmh. If the round trip took a total of 3 hours, how many minutes did it take Cole to drive to work?	Choose the correct choice from the following options
A) 66 B) 70 C) 72 D) 85 E) 108
First round distance travelled (say) = d   Speed = 80 k/h   Time taken, T2 = d/80 hr   Second round distance traveled = d (same distance)   Speed = 120 k/h   Time taken, T2 = d/120 hr   Total time taken = 3 hrs   Therefore , 3 = d/80 + d/120   LCM of 80 and 120 = 240   3= d/80 + d/120   =&gt; 3 = 3d/240 + 2d/240   =&gt; d = 240 * 2/ 5 Km   Therefore, T1= d/80   =&gt; T1 = (240 *3) / (5 x 80)   =&gt; T1 = (9 x 60) / 5 -- in minutes   =&gt; T1 = 108 minutes.   108
