A delivery vehicle travels at 72 km/h. How many meters does it cover in 15 seconds?
Correct Answer: Option C
Explanation:
Speed = 72 * (5/18) = 20 m/s. Distance = Speed * Time = 20 * 15 = 300 meters.
Speed = 72 * (5/18) = 20 m/s. Distance = Speed * Time = 20 * 15 = 300 meters.

A train 150 meters long passes a pole in 7.5 seconds. What is the speed of the train in km/h?
Correct Answer: Option D
Explanation:
Speed of train = 150 / 7.5 = 20 m/s. In km/h = 20 * (18/5) = 72 km/h.
Speed of train = 150 / 7.5 = 20 m/s. In km/h = 20 * (18/5) = 72 km/h.

A baseline boat hull can row 10 km/h in still water. If the river current tracks a velocity of 2 km/h, find the exact sector distance covered downstream by the boat hull in 30 minutes flat.
Correct Answer: Option C
Explanation:
Downstream speed = 10 + 2 = 12 km/h. Time = 30 minutes = 0.5 hour. Distance covered = Speed * Time = 12 * 0.5 = 6 km.
Downstream speed = 10 + 2 = 12 km/h. Time = 30 minutes = 0.5 hour. Distance covered = Speed * Time = 12 * 0.5 = 6 km.
