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. 
thanks

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

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.

ok

Reiny, how can you show me how to do the last part wirten out?
Thank you so much!
