your friend drove 3 hrs x 52 miles per hour = 156 miles.
therefore you have 300-156 = 144 miles left to drive and 3 hours to do it. 144 miles/ 3 hours = ???

3 hours X 52 mph = 156 miles
300 miles - 156 miles = 144 miles
144 miles divided by 3 hours = 48 miles per hour

3 hours * 52 miles /hour = 156 miles
300 - 156 = 144 miles to go
144 miles / 3 hours = 48 miles per hour.

friend drove for 3 hr at 52 mi/hr. it means friend drove 52 x 3 mi = 156 mi.
distance left to drive is 300 - 156 = 144 mi.
To get to the hotel (144 mi away) in 3 hrs your need to drive 144/3 = 48 mi/hr .

your friend drives 3*52=156miles
so you have to drive 300-156=144 miles in three hours.
144/3=48miles per hour

52*3=156
300-156=144
144/3=48
You would have to drive 48 mph.
