Correct Answer - Option 4 : 25 km/hr
Given:
Speed = 40 km/hr
Required time = 5 hour
Concept Used:
Distance covered = Speed × Time
Calculation:
The car covered total distance = 40 × 5 = 200 km
The car will cover the same distance in 8 hours
Required speed = 200/8 km/hr
⇒ 25 km/hr
∴ The speed of the car should be 25 km/hr.
