    [SOLVED] SAT math page 673

    The figure below shows the route Diane has to take. Diane travels 16 miles from A to B, 15 miles from B to C, and 4 miles from C to D. If she was able to travel from A to D directly, how much shorter, in miles, would the trip be?

    I got the total original to be 35 miles. How do I find the 'shorter' trip? Thanks in advance

    Hi again

    Note the difference !
    - it's not the "shorter trip"
    - it's "if she travels from A to D directly, how much shorter will it be ?" that is to say 35 minus AD

    Please see the attachment. You'll have to find distance AD. Think "Pythagoras".
