Answer 1

Given:

Initial Speed = 80 km/h

Time taken at initial speed = 14 hours

Time taken at new speed = 20 hours

Formula used:

Distance = Speed × Time

Since the distance is the same for both cases:

New Speed = \(\dfrac{\text{Initial Speed} \times \text{Initial Time}}{\text{New Time}}\)

Calculation:

New Speed = \(\dfrac{80 \times 14}{20}\)

⇒ New Speed = \(\dfrac{1120}{20}\)

⇒ New Speed = 56 km/h

∴ The correct answer is option (4).
