D Correct answer
Explanation

Bike speed = 288/8 = 36 km/h. Car speed = 2 * 36 = 72 km/h. Bus speed = 3/4 * 72 = 54 km/h. Distance covered by bus in 5 hours = 54 * 5 = 270 km. Distance left = 288 - 270 = 18 km.

AI explanation

The bike covers 288 km in 8 hours, so the speed of the bike is 36 km/hr. The car's speed is double the bike's speed, making it 72 km/hr, and 3/4 of the car's speed gives the bus speed: 54 km/hr. In 5 hours, the bus travels a distance of 5 hr * 54 km/hr = 270 km. Subtracting this from the total distance of 288 km leaves 18 km uncovered.
