A car travels 80 km at the speed of 20 km/h and the next 30 km at the speed of 30 km/h. What is its average speed?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is Option 1 i.e. 22 km/h.

Time₁ = 802080 \over 20 = 4 hr

Time₂ = 303030 \over 30 = 1 hr

Total Distance = 80 + 30 = 110 km

Total Time = 4 + 1 = 5 hr

Average Speed = 1105110 \over 5 = 22 km/h
