A bus travels a distance of 240 km in 4 hours. If the bus increases its speed by 20 km/h, how much time will it take to cover the same distance?

1. 3 h
2. 2.5 h
3. 3.5 h
4. 4 h

Correct answer: 3 h

Solution

The original speed is $240/4 = 60$ km/h. After increasing by 20 km/h, the speed becomes 80 km/h, so time taken is $240/80 = 3$ hours.
