Mary drove from Amity to Belleville at a speed of 50 mi/h. On the way back, she drove at 60 mi/h. The total trip took 4(2/5)h of driving time. Find the distance between there two cities

  • algebra -

    Let the distance each way be d
    time for 1st trip = d/50
    time for 2nd trip = d/60

    d/50 + d/60 = 4.4
    times 300
    6d + 5d = 1320
    11d = 1320
    d = 120

    distance between towns is 120 mi
