SSC CHSL - 12 April 2021 - Shift 1 • Quantitative Aptitude • Q71

A car covers a distance of 48 km at a speed of 40 km/h and another 52 km with a speed of 65 km/h. What is the average speed of the car (in km/h) for the total distance covered?

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. 50

Total Distance traveled = 48 km + 52 km

⇒ 100 km

Total Time = (48/40) + (52/65) 

⇒ 6/5 + 4/5 = 2 hours 

Average Speed = (100/2)

The required Average Speed = 50 km/h
