Question
A train has to cover a distance of 900 km in 25 hours. What should be its average speed in meters/second?Options20101836
Solution
To find the average speed, we need to divide the total distance by the total time.
Step 1: Convert the distance from km to meters. 1 km = 1000 meters So, 900 km = 900 * 1000 = 900,000 meters
Step 2: Convert the time from hours to seconds. 1 hour = 3600 seconds So, 25 hours = 25 * 3600 = 90,000 seconds
Step 3: Calculate the average speed. Average speed = Total distance / Total time = 900,000 meters / 90,000 seconds = 10 meters/second
So, the average speed of the train should be 10 meters/second.
