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?
Distance = 8-mile
Initial speed = 55 miles per hour
initial time = 8/55 hours = 8*60/55 minutes
New speed = 35 miles per hour
new time = 8/35 hours = 8*60/35 minutes
Difference in time in minutes = 8*60/35 - 8*60/55 = 4.9
IMO A
