A car travels 100 km in the first two hours, stops for half an hour, and then travels 200 km in the next four hours. Find the average speed of the car.

Asked by nngonzalez22

Answer (3)

Average speed = (total distance) / (total time)
Total distance = 100 km + 200 km = 300 km
Total time = 2 hrs (first part) + 1/2 hr (stop) + 4 hrs (second part) = 6.5 hrs
Average speed = 300 / 6.5 = 46.154 km/hr (rounded)

The average speed of the car is calculated by dividing the total distance of 300 km by the total time of 6.5 hours, which gives an average speed of approximately 46.15 km/h. This takes into account the car's travel time and the stop it made. Therefore, the average speed is roughly 46.15 km/h .
