✮ Question

• A body covers 10 m in the first 5 s and 20 m in the next 5 s. Find its average speed​

✮ Answer

• Average speed = 3 m/s

✮ Explanation :

We know:

• Average speed = Total Distance covered / Total Time Taken

Average speed = Total Distance covered / Total Time Taken

⇒ Average speed = (10 m + 20m) / (5s + 5s)

⇒ Average speed = 30m / 10 s

⇒ Average speed = 3 m/s
