You jog at 9.50 km/ h for 8.00 km; then you jump into a car and ride an additional 16.0 km. What average speed must the car have for the average speed for the entire 24.0-km trip to be 24 km/h ?

Respuesta :

In this question, you are given the jog velocity( 9.5km/h), jog distance(8km), car travel distance (16km) and the average speed of entire trip (24km/h). Then to calculate the speed of the car, the calculation would be:

24km / (24km/h) = 8km/ (9.5km/h) + 16km/ car speed
1h- 0.8421 h= 16km/car speed
car speed = 16km/ 0.158h= 101 km/h
