A car travelled a distance of 8km in 80seconds. Find the speed in metre per seconds

To find the speed in meters per second, we need to convert both the distance and the time to meters and seconds respectively.

Given:
Distance = 8 km
Time = 80 seconds

1 kilometer = 1000 meters
So, 8 km = 8 * 1000 = 8000 meters

Therefore, the distance is 8000 meters and the time is 80 seconds.

Speed = Distance/Time
Speed = 8000 meters/80 seconds
Speed = 100 meters/second

Hence, the speed of the car is 100 meters per second.
