C Correct answer
Explanation

Distance = 90 km/hr * 10 hr = 900 km. New speed required = 900 km / 4 hr = 225 km/hr. Increase in speed = 225 - 90 = 135 km/hr.

AI explanation

The total distance of the journey is 90 km/hr multiplied by 10 hours, which equals 900 km. To cover this distance in 4 hours, the required speed is 900 km divided by 4 hours, resulting in 225 km/hr. The increase in speed is the new speed minus the original speed, giving 225 km/hr minus 90 km/hr, which equals 135 km/hr.
