Determine the average speed for the trip

Reference no: EM13557365

A person travels by car from one city to another with different constant speeds between pairs of cities. She drives for40.0 min at 50.0 km/h, 7.0 min at70.0 km/h and 35.0 min at 30.0km/h, and spends 35.0 min eating lunchand buying gas.

(a) Determine the average speed for the trip.
(b) Determine the distance between the initial and final cities along this route.
