A person travels by car from one city to another with

A person travels by car from one city to another with different constant speeds between pairs of cities. She drives for 20.0 min at 60.0 km/h, 17.0 min at 95.0 km/h and 35.0 min at 40.0 km/h, and spends 55.0 min eating lunch and buying gas.

(a) Determine the average speed for the trip.

km/h

(b) Determine the distance between the initial and final cities along this route.
