D Correct answer
Explanation

Car speed = 66 km/hr. Time = 528 / 66 = 8 hours. Truck speed = 66 - 24 = 42 km/hr. Truck time = 8 + 7 = 15 hours. Distance = 42 * 15 = 630 km.

AI explanation

Using the formula Time equals Distance divided by Speed, the time taken by the car is 528 divided by 66, which equals 8 hours. The truck's speed is 66 minus 24, giving 42 km/hr, and its travel time is 8 plus 7, giving 15 hours. Applying the Distance formula, the truck covers 42 multiplied by 15, which equals 630 km.
