Two cars leave town at the same time going in opposite direactions.One travels 44 mi/h and the other 55 mi/h. In how many hours will they be 297 miles apart?

  • algebra -

    Let that time be t hours
    then
    44t + 55t = 297
    99t = 297
    t = 297/9
    = 37 hours

    check: in 3 hours first car went 3(44) or 132 mi
    second car went 3(55) or 165 miles
    total = 297 , close enough

  • algebra -

    I think that's right
