One of your friends is heading north for the Christmas holiday and the other friend is heading south.If their destines are 1029 miles apart and one car is traveling at 45 miles per hour and the other car is traveling at 53 miles per hour.How many hours before the two cars pass each other?

  • Math -

    Why should they pass each other at all? Aren't they going in opposite directions, away from each other?

    Are they following a great circle route around the earth?

  • Math -

    I am thinking that they must be due north/South of each other in the beginning, and the on going South started out as the north most .

    Their relative velocity is 53+45=98mi/hr

    To meet, they travel a combined 1029 mi.

    d=rt
    1029=98*t
    solve for t, the time of meeting.
