Correct Answer: Option C
Let the speed of the 1st trip be x miles/hr
and the speed of the 2nd trip be 3x miles/hr
Speed = distance/time
∴ Time taken to cover a distance of 50 miles on the 1st trip
time taken to cover a distance of 300 miles on the next trip
∴the new time compared with the old time is twice as much
