You walk from chisale to st Francis a distance of 6km/h and 50minutes, the average speed in m/s will be 2m/s
What is average speed ?
The average speed of a moving object is defined as the total distance covered by it divided by the total time taken.
The S.I unit of speed is meter per second. Speed is also measured in kilometer per hour.
Average speed is a scaler quantity
Average speed is the total distance travelled by an object to the total time taken. However, average velocity is the change in position or displacement (∆x) divided by the time intervals (∆t) in which the displacement occurs. No matter how many times the speed has been changed to travel the entire distance , average speed is that constant speed value with which one can travel by and reach the same distance in same amount of time .
It can be calculated with a formula average speed = distance / time
given
distance = 6 km = 6000 m
time = 50 minutes = 50 * 60 = 3000 sec
average speed = distance / time
= 6000 / 3000 = 2m/s
