Answer 1

Given :- A bus travels at v km/hr. It is going from Lucknow to Gorakhpur. After the bus has travelled for 5 hours, Gorakhpur is still 20 km away. What is the distance from Lucknow to Gorakhpur ? Express it using v.

Solution :-

→ Speed of bus = v km/h

so,

→ In 5 hours bus travelled distance = speed * time = v * 5 = 5v km.

now, given that, after travelling for 5 hours , Gorakhpur is still 20 km away .

therefore,

→ The distance from Lucknow to Gorakhpur = Distance covered + Distance left .

→ The distance from Lucknow to Gorakhpur = 5v + 20 = 5(v + 4) km (Ans.)

Hence, the distance from Lucknow to Gorakhpur is 5(v + 4) km .
