Question
Quantity I: A car travels at a speed of 60 km/hr for the
first 3 hours, and then at 80 km/hr for the next 2 hours. Find the average speed of the car for the entire journey. Quantity II: A truck travels 150 km at 50 km/hr, and then another 180 km at 60 km/hr. Find the average speed of the truck for the entire journey.Solution
Distance = (60 * 3) + (80 * 2) = 180 + 160 = 340 km Total time = 3 + 2 = 5 hours Average speed = 340 / 5 = 68 km/hr Quantity II: Total distance = 150 + 180 = 330 km Total time = (150 / 50) + (180 / 60) = 3 + 3 = 6 hours Average speed = 330 / 6 = 55 km/hr Answer: E (Quantity I > Quantity II)
