A motorcyclist rides his motorcycle at a speed of 90 km/hr in the first hour and then next two hours at a speed of 120 km/hr. Find the average speed of the rider.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 110 km/hr.
Distance traveled in the first hour = 90 × 1 = 90 km
Distance traveled in the next two hours = 120 × 2 = 240 km
Total Distance = 90 + 240 = 330 km
Total Time = 1 + 2 = 3 hours
Average Speed = 330/3 = 110 km/hr
