The cars must have had the same Average Speed

Average speed is the mean value of the speed of a body over a period of time. The formula for average speed is needed since the speed of a moving body is not constant and varies across a period of time. Even with varying speed, the values of total time and the total distance covered can be used, and with the help of the formula for average speed, we can find a single value to represent the entire motion.

The average speed of a body is equal to the total distance covered, divided by the total time taken. The formula for average speed is given as:

[tex]\frac{Total distance covered by the object}{Total time taken}[/tex]

Given :-  

  • Distance covered by A = 30 meters
  • Time taken by A = 5 seconds
  • Distance covered by B = 42 meters
  • Time taken by B = 6 seconds

Substituting the given values in the formula for A and B respectively we get

Average Speed of A = [tex]\frac{30}{5}[/tex] m/s = 6 m/s

Average Speed of B = [tex]\frac{42}{7}[/tex] m/s = 6m/s

Thus the cars must have had the same Average Speed.
