✭ Two buses A & B take a journey of 200 km
✭ Bus A travels with a speed of 50 km/h one way and 40 km/h while coming back
✭ Bus B takes 45 km/h on both the journeys
◈ Which bus takes less time to cover the to & fro distance?
◈ Do they both take the same time?

Bus B
This bus travels with the same speed on both the journeys,
- Speed = 45 km/h
- Distance = 200 km
Substituting the given values,
