Average speed = total distance covered / total time taken

So,

Average speed = 400 / 210

= 40 / 21 m/s

Answer 2

Answer:

19.046 m/s

Explanation:

Given:

• Distance covered by the object = 400 metres
• Time taken by the object to cover a distance of 400 metres = 210 seconds

To find:

• Average speed of the object which covers 400 metres in 210 seconds

Average speed = $\frac{Total \ distance }{Total \ time}$

In this case:

Total distance = 400 metres

Total time = 210 seconds

Average speed = $\frac{400}{210}$

Average speed = $19.046.. m/s$

The average speed of the object is equal to 19.046 m/s
