D Correct answer
Explanation

First, calculate the distance: Speed × Time = 60 km/hr × (40/60) hr = 40 km. To cover the same 40 km in 32 minutes (32/60 = 8/15 hours), the required speed is Distance/Time = 40 ÷ (8/15) = 40 × (15/8) = 75 km/hr. Speed and time are inversely proportional when distance is constant.
