Respuesta :
Average speed of the car be 25 meter/second.
What is speed?
Speed is characterized as the rate at which an object's position changes in any direction.
The distance travelled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity. SI unit of speed be meter/second.
Given parameters:
Distance travelled by the car: s = 500 m.
Time taken by the car: T = 20 second.
So, speed of the car be = distance travelled/time taken
= 500/20 meter/second
= 25 meter/second.
Hence, its average speed be 25 meter/second.
