math

Danny and Erica are 3km apart on a straight road. They set out to walk uniformly at the same time. If they walk in an opposite direction, they will meet after 24 minutes. If they walk in the same direction, Danny will catch up to Erica after 6 hours. Find each Individual's speed in km/h.

I'm fine with solving the equation, it's just setting it up which confuses me :L Thanks for any help in advanced.

  1. let Danny's speed be d km/h
    let Erica's speed by e km/h

    If they walk towards each other .... 24 min = 2/5 hr,
    (2/5)d + (2/5)e = 3

    It they walk in the same direction ... clearly Danny walks faster
    6d - 6e = 3

    solve the two equations, let me know what you get
