A bus travelling at 86 km/hr completes a journey in 7 hours. What should be its speed to cover the same distance in 14 hours?​

Correct option is A

Given:

Speed of the bus = 86 km/hr

Time taken = 7 hours

Same distance to be covered in = 14 hours

Find the required speed.

Formula Used:

Distance = Speed × Time

For the same distance, speed is inversely proportional to time.

Solution:

Distance covered = 86 × 7 = 602 km

Required speed = $$\frac{602}{14}$$​ = 43 km/hr

Required speed = 43 km/hr

Alternate Solution:

Time is doubled (7 → 14 hours), so speed becomes half:

86 ÷ 2 = 43 km/hr
