Two towns are 420 miles apart. A car leaves the first town traveling toward the second town at 55 mph. At the same time, a second car leaves the other town and heads toward the first town at 65 mph. How long will it take for the two cars to meet?

  • Math - ,

    the distance traversed is 420miles
    the combined velocity is 120

    time=distance/velocity

  • Math - ,

    If you don't visualize that, here is a more traditional approach.
    the first car travels=55*t
    the second car travels=60t
    they both travel 420

    distance=velocity*time
    420=55t+65t=120t
    or t=420/120

    thank you, i have trouble "translating" a word problem to an equation, but thanks!
