Answer / guest
75 miles per hour
While going to the destination, the vehicle travels 10 mils
at the speed of 50 miles per hour. So the time taken to
travel 10 miles is
= (60 * 10) / 50
= 12 minutes
Now it's given that round-trip travel time is 20 minutes. So
the vehicle should complete its return trip of 10 miles in 8
minutes. So the speed of the vehicle must
= (60 * 10) / 8
= 75 miles per hour
