Question: If a train travels 120 km in 2 hours and then 180 km in 3 hours, what is the average speed of the train for the entire journey?

Options:

Correct Answer: 60 km/h

Solution:

Total distance = 120 + 180 = 300 km. Total time = 2 + 3 = 5 hours. Average speed = Total distance / Total time = 300 km / 5 hours = 60 km/h.

If a train travels 120 km in 2 hours and then 180 km in 3 hours, what is the average speed of the train for the entire journey?

If a train travels 120 km in 2 hours and then 180 km in 3 hours, what is the average speed of the train for the entire journey?

Step 1: Find the distance traveled in the first part of the journey, which is 120 km.
Step 2: Find the distance traveled in the second part of the journey, which is 180 km.
Step 3: Add the two distances together to find the total distance: 120 km + 180 km = 300 km.
Step 4: Find the time taken for the first part of the journey, which is 2 hours.
Step 5: Find the time taken for the second part of the journey, which is 3 hours.
Step 6: Add the two times together to find the total time: 2 hours + 3 hours = 5 hours.
Step 7: Calculate the average speed by dividing the total distance by the total time: 300 km / 5 hours.
Step 8: The average speed is 60 km/h.

Average Speed – Average speed is calculated by dividing the total distance traveled by the total time taken.
Distance and Time Calculation – Understanding how to sum distances and times correctly is essential for calculating average speed.
