Due to construction, the speed limit along an 8-mile section of highway is reduced from 55 miles per hour to 35 miles per hour. Approximately how many minutes more will it take to travel along this section of highway at the new speed limit than it would have taken at the old speed limit ?  Options:
A) 5
B) 8
C) 10
D) 15
E) 24
Let t1 is time taken @ 55 mph   t1 = 8/55   Let t2 is time taken @ 35 mph   t2 = 8/35   Difference in time = 8/35 - 8/55 = 8 * 20 / (35 * 55) hr = 160 * 60 / (35 * 55) mins = 4.7 = 5 (approx) mins   5NSWER:5
