It takes Jenna 60 min to drive to work in the morning. She drives home using the same route, but it takes 25 min longer, and, averages 20m/hr less than in the morning. How far does Jenna drive to work?

  • Math -

    d = V1*T1 = V2*T2.
    V1 * 1 = V2*(60+25)/60,
    V1 = V2*1.4

  • Math -

    V1 = V2*1.42,
    V1 = (V1-20)*1.42,
    V1 = 67.7 Mi/h.

    d = V1*T1 = 67.7mi/h * 1h = 67.7 m1.
