Unless otherwise specified, cite all answers in SI units, and to three significant figures. A woman drives a car from one city to another with different constant speeds along the trip. She drives at a speed of 26 km/h for 20.0 min, 58 km/h for 15.0 min, makes a stop for 58 min, then continues at 29 km/h for 43 min, at which point she reaches her destination. What is her average velocity for the entire trip, in km/hr?
