Question
Which of the following is the correct relation between
Quantity I and Quantity II? Quantity I: A train travels at a speed of 45 km/h for the first 3 hours, and then at a speed of 60 km/h for the next 4 hours. Find the total distance covered by the train. Quantity II: A train travels at a speed of 50 km/h for the first 5 hours, and then at a speed of 70 km/h for the next 3 hours. Find the total distance covered by the train.Solution
Quantity I: Distance = Speed × Time For the first part: Distance = 45 × 3 = 135 km For the second part: Distance = 60 × 4 = 240 km Total distance covered = 135 + 240 = 375 km Quantity II:                        For the first part: Distance = 50 × 5 = 250 km For the second part: Distance = 70 × 3 = 210 km Total distance covered = 250 + 210 = 460 km Comparing Quantity I and Quantity II: Quantity I = 375 km Quantity II = 460 km Now, comparing: Quantity I < Quantity II Therefore, the correct option is: C
