Question

A car travels at 50 km/hr for 2 hours. It then travels an additional distance of 23 km in 4 hour. The average speed of the car for the entire trip is(in km/hr),

Answer 1

Distance travelled in 2 hours = 50 km/hr x 2 hrs = 100 km

Distance travelled in 4 hours = 23 km

Total distance travelled = 100 km + 23 km = 123 km

Total time taken = 2 hrs + 4 hrs = 6 hrs

Average speed = Total distance/Total time

Average speed = 123 km/6 hrs

Average speed = 20.5 km/hr
