Sandy takes a trip in her car from New York City to
Manhattan. For the first 32.0 minutes she travels with a speed
of 81.1 km/h. She then spends 17 minutes at the gas station. Once
she starts up again she drives for 13.0 minutes at 99.6 km/h, and
then drives 44.0 minutes at 41.1 km/h.
a. Sketch a position vs. time graph for her trip.
b. Assuming Sandy traveled in a straight line, determine the
distance in kilometers she traveled between the two cities.
c. Determine the average speed for the trip in km/h.
