Steve McSpoke left home on his bicycle at 8am, traveling at 18km/h. At 10am, Steve's brother set out after him on a motorcycle, following the same route. The motorcycle traveled at 54km/h. How long had steve traveled when his brother overtook him?

Steve's brother time to catchup  t hrs
Steve's time to catchup by brother  t+2
54t = 18(t+2)
54t = 18t + 36
36t = 36
t = 1
Steve had biked for 3 hours, when his brother overtook him.

Also, how far had steve traveled when his brother overtook him?

math  Reiny, Wednesday, January 2, 2013 at 5:38pm
simply sub in the value of t = 1 into both distances., you will obviously get the same answer since they both went the same distance.
