10. A person travels by car from one city to another with different constant speeds between pairs of cities. She drives for 25.0 min at 75.0 km/h, 16.0 min at 100.0 km/h, and 40.0 min at 50.0 km/h and spends 30.0 min eating lunch and buying gas. Determine the average speed for the trip. (km/h) Determine the distance between the initial and final cities along the route. (km)

Question

10. A person travels by car from one city to another with different constant speeds between pairs of cities. She drives for 25.0 min at 75.0 km/h, 16.0 min at 100.0 km/h, and 40.0 min at 50.0 km/h and spends 30.0 min eating lunch and buying gas. Determine the average speed for the trip. (km/h) Determine the distance between the initial and final cities along the route. (km)

Expert Solution
Step 1

Given:

The speed of the car for 25 min is 75 km/h.

The speed of the car for 16.0 min is 100.0 km/h.

The speed of the car for 40 min is 50.0 km/h.

The driver spends time eating and lunch is 30.0 min.
