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 100.0 km/h, 18.0 min at 65.0 km/h, and 45.0 min at 50.0 km/h and spends 15.0 min eating lunch and buying gas. (a) Determine the average speed for the trip. 54.3 km/h eBook (b) Determine the distance between the initial and final cities along the route. x Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. km
