A bus travelling at 80 km/h completes a journey in 14 hours. At what speed will it have to cover the same distance in 20 hours?

Correct option is C

Given:

Speed = 80 km/h

Time taken = 14 hours

New time = 20 hours

Formula Used:

Distance = Speed × Time

Solution: 

Distance = 80 × 14 

Now, 

New Speed = $$\frac{80 \times 14}{20}$$​​

$$= \frac{1120}{20}$$​ = 56 km/h
