part 1
Simpson drives his car with an average veloc-
ity of 47.5 km/h to the east.
How long will it take him to drive 137 km
on a straight highway?
Answer in units of h

part 2
How much time would Simpson save by in-
creasing his average velocity to 105 km/h to
the east?
Answer in units of min

  1. 1. d = Vt,
    t = d / V = 137 / 47.5 = 2.88h.

    2. t = 137 / 105 = 1.3h.

    Ts=2.88 - 1.3 = 1.58h = 94.5min. = Time saved.
