If Connor was still 60 miles ahead at 3pm, how fast was Trent driving in terms of miles per hour?

Question

Connor began driving from Trent at 60 miles per hour at 9am, 2 hours before Trent started out to catch him. If Connor was still 60 miles ahead at 3pm, how fast was Trent driving in terms of miles per hour?

Answer 1

distance = rate x time and rate = distance/time

Connor travels for 6 hrs @ 60 mi/hr = 360 mi.

Trent travels for 4 hrs (starts 2 hrs after Connor, at 11 am) @ x miles/hr. At 3 pm Trent is 60 miles behind, so he only traveled 300 mi. by 3 pm. His average speed must be 300/4 = 75 mph.
