Distance Question

  1. Dec 22, 2004 #1
    A boy cycling to school at c miles per hour passes a boy walking there at w miles per hour. 10 minutes later, the cyclist reaches school. How many minutes after that does the other boy reach school?

    I know d= 10c.

    The difference in their speeds is c - w. I would I find the amount of time after the other boy reaches school?

    Thanks

    we have distance = 10c
    So time taken by the boy who is walking = 10c/w minutes
    S0 the person walking will reach school 10c/w-10 minutes after the cyclist .
    One interesting thing is the expression can be re wirtten as 10(c-w)/w. 10(c-w) being the relative distance and w being the velocity ...

    regards
