    Ok so the first plane has 2 hours head start

    means 2 times 500=1000=1000mile head start

    so now

    3100-1000=2100

    in how many hours will the conbined planes travel 2100

    500+550=1050

    1050 times how many hours=2100

    divide both sides by 1050

    hours=2

    4pm was our base time

    4+2=6

    answer is 6PM
