Question
A train travels 120 km at a speed of 60 km/h and then
travels another 80 km at a speed of 40 km/h. What is the average speed for the entire journey?Solution
The total distance = 120 km + 80 km = 200 km. The time taken for the first part of the journey = 120 km / 60 km/h = 2 hours. The time taken for the second part of the journey = 80 km / 40 km/h = 2 hours. So, the total time = 2 hours + 2 hours = 4 hours. The average speed = Total distance / Total time = 200 km / 4 hours = 50 km/h. Correct option: b
