a train travel at 80 km per hour.calculate the average speed of the train in metres per second
80 km/hr * 1000m/km * 1hr/3600s = 80000/3600 m/s
To calculate the average speed of the train in meters per second, we need to convert the speed from kilometers per hour to meters per second.
Step 1: Convert kilometers per hour to meters per hour
Since 1 kilometer is equal to 1000 meters, we can multiply the speed in kilometers per hour by 1000 to convert it to meters per hour.
80 km/h * 1000 m/km = 80000 m/h
Step 2: Convert meters per hour to meters per second
To convert meters per hour to meters per second, we divide the speed in meters per hour by the number of seconds in an hour, which is 3600.
80000 m/h รท 3600 s/h = 22.22 m/s (rounded to two decimal places)
So, the average speed of the train in meters per second is approximately 22.22 m/s.
