Highway speed limit increased from 55 mi/h to 65 mi/h, how much time is saved on a 435 mile trip if you travel at the new speed limit?

  • Physics -

    Time for first speed
    T1=435/55=7.909hrs
    T2=435/65=6.96hrs
    Time saved=
    7.909-6.969=1.21
    Therefore the time saved
    is 1 hr 21 mins
