Question

Tim started out traveling at 60 km/h. Two hours later, Mike left from the same point. He drove along the rode at 80 km/h. How many hours does Mike have to drive to catch up with Tim?

Answer 1

They travel the same distance, an time is off by hours.

d= 60km/h * timeTim
d=80km/h*(timeTim-2)
set them equal, solve for Tim's time. Subract two,and you have mikes time
check my thinking.
