Question 78082: Martina leaves home at 9 a.m., bicycling at a rate of 24 mi/h. Two hours later, John leaves, driving at the rate of 48 mi/h. At what time will John catch up with Martina? Answer by checkley75(3666) (Show Source):
You can put this solution on YOUR website! 24*x=48(x-2)
24x=48x-96
24x-48x=-96
-24x=-96
x=-96/-24
x=4 hours after Martina leave John will catch her.
proof
24*4=48*2
96=96 miles from the start is where they meet.
