Aptitude:speed and distance [Section 1 of 1] Q24 of 30 Marks 1 General Instructions 100% ×CloseTest time left: 06:13Select the correct answerA train has to cover a distance of 900 km in 25 hours. What should be its average speed in meters/second?
Solution
To find the average speed, we need to divide the total distance by the total time.
-
Convert the distance from kilometers to meters. 1 kilometer is equal to 1000 meters. So, 900 kilometers is equal to 900 * 1000 = 900,000 meters.
-
Convert the time from hours to seconds. 1 hour is equal to 3600 seconds. So, 25 hours is equal to 25 * 3600 = 90,000 seconds.
-
Now, divide the total distance by the total time to find the average speed. So, the average speed is 900,000 meters / 90,000 seconds = 10 meters/second.
So, the average speed of the train should be 10 meters/second.
