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?

  • math - ,

    Steve's brother time to catch-up --- t hrs
    Steve's time to catch-up 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.

    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.
