A boy rides his bicycle 10 km at an average speed of 12 km/hr and again travels 12 km at an average speed of 10 km/hr. His average speed for the entire trip is approximately

10.4 km/hr

10.8 km/hr

11 km/hr

12.2 km/hr

Explanation:

Total Distance = 10 +12 = 22 km
Total time = 10/12 + 12/10 = 5/6 + 6/5

= 25/30 + 36/30 = 61/30 hours
Average speed = 22 / 61/30 = 660/61 = 10.8 km/ hour

Hence, option 2 is the correct answer.
