Explanation:
- Shital travels a certain distance in 9 hours at 40 km/h.
- Calculate the distance: Distance = Speed x Time = 40 km/h x 9 hours = 360 km.
- She wants to cover the same distance in 6 hours.
- To find the required speed: Required Speed = Distance / Time = 360 km / 6 hours = 60 km/h.
- Calculate the increase in speed: Increase = 60 km/h - 40 km/h = 20 km/h.
- Correct Answer: Option 4, 20 km/h
