Question

) I went from my house to a playground, 300

metres away in 10 minutes. I ran back and
reached in 2 minutes. What was my average
speed? give answer fast!

Answer 1

v = 0.834 m/s or 3 km/h

Explanation:

Given that,

Distance between house and playground is 300 meters

If you went 300 metres away in 10 minutes and ran back and reached in 2 minutes, it means total distance covered by you during whole journey is 300 m + 300 m = 600 m

Total time, t = 10 min + 2 min = 12 min = 720 seconds

Total distance covered divided by total time gives average speed. So,

`v=(600\ m)/(720\ s)\\\\v=0.834\ m/s`

or

v = 3 km/h

So, the average speed is 0.834 m/s or 3 km/h.
