A car travels with the speed of 40 km/hr for the first hour and 60 km/hr for the next hour. What will be the average speed of the car?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 50 km/hr.
Average speed = Total Distance/Total time
We have,
Total Distance = 40 + 60 = 100 km
Total Time = 2 hour
Hence, Average speed = 100/2 = 50 km/h
