A car travels from A to B at the speed of 40 km/hr and travels from B to A at speed of 60 km/hr. What is the average speed (in km/hr) of the car?
Show answer & explanation
Correct answer: B
Explanation
Given:
Speed from A to B = 40 km/h
Speed from B to A = 60 km/h
According to the formula:
Average Speed = (2 × v₁ × v₂) / (v₁ + v₂)
Average Speed = (2 × 40 × 60) / (40 + 60)
= 4800 / 100
= 48 km/h
