Answer :
The average speed of round trip is 1192.8 m/s
Average speed of the round trip is
2*994*1491/(994+1491)
= 1192.8 m/s
- The overall distance the object covers in a given amount of time is its average speed.
- A scalar value represents the average speed. It has no direction and is indicated by the magnitude.
- The mean value of a body's speed over a period of time is its average speed.
- Since a moving body's speed is not constant over time and fluctuates, the average speed formula is required. The numbers of total time and total distance travelled can be used even with fluctuating speed.
