g A drone is flying at 150 kilometers per hour at a constant altitude of 2 km above a straight road. The drone pilot uses radar to determine that an oncoming motorcycle is at a distance of exactly 4 kilometers from the drone, and that this distance is decreasing at 200 kph. Find the speed (in kph) of the motorcycle. Hint: At the end, remember to consider that the drone is moving towards the motorcycle at 150 kph. Speed cannot be negative. Note: Round to the nearest tenth.
