Mathematics
A bus travels at v km per hour. It is going from Delhi to Jaipur. After the bus has travelled 5 hours, Jaipur is still 20 km away. What is the distance from Delhi to Jaipur?
Answer
Speed of the bus = v km/h
Time travelled = 5 hours
Distance covered in 5 hours = speed × time = 5v km
Remaining distance to Jaipur = 20 km
Total distance from Delhi to Jaipur = Distance covered + Remaining distance = 5v + 20
Hence, the distance from Delhi to Jaipur is (5v + 20) km.
