A bus travelling at 99 km/h completes a journey in 14 hours. At what speed will it haveto cover the same distance in 18 hours?

Correct option is A

Given:

Speed of the bus = 99 km/h

Time taken for the journey = 14 hours

Required time to cover the same distance = 18 hours

Formula Used:

Distance = Speed × Time

Solution:

Distance = 99km/h × 14hours = 1386km

Calculate the required speed to cover 1386 km in 18 hours:

Required Speed = $$\frac{1386}{18 }$$​ = 77 km/h

Thus, the required speed is 77 km/h
