Note: Your question inputs seem a little odd. But, I am assuming that you really mean '10km in 5 ms'.
Answer:
The Average speed = 15000 / 0.005 = 3000000 m/s
Step-by-step explanation:
- Average speed can be calculated by dividing the total distance covered by the total time.
Average speed = Total Distance / Total time
Given
- Total distance = 15km = 15(1000) = 15000 m
- Total time = 5 ms = 0.005 seconds
Thus,
Average speed = Total Distance / Total time
Average speed = 15000 / 0.005 = 3000000 m/s
