Question
A train has to cover a distance of 900 km in 25 hours. What should be its average speed in meters/second?
Solution
Sure, here are the steps to solve this problem:
-
First, we need to convert the distance from kilometers to meters. We know that 1 kilometer is equal to 1000 meters. So, 900 kilometers is equal to 900 * 1000 = 900,000 meters.
-
Next, we need to convert the time from hours to seconds. We know that 1 hour is equal to 3600 seconds. So, 25 hours is equal to 25 * 3600 = 90,000 seconds.
-
Now, we can calculate the average speed by dividing the total distance by the total time. So, the average speed is 900,000 meters / 90,000 seconds = 10 meters/second.
So, the train should have an average speed of 10 meters/second to cover a distance of 900 km in 25 hours.
