A boy walks 50metres in 30 seconds.what is his speed in km/h

Answer 1

To find the speed in km/h, we need to convert the distance from meters to kilometers and the time from seconds to hours.

1 kilometer = 1000 meters
1 hour = 3600 seconds

So, the boy walks 50 meters in 30 seconds:

(50 meters / 1000) kilometers = 0.05 kilometers
(30 seconds / 3600) hours = 0.00833333333 hours

Now, we can calculate his speed:

speed = distance/time
speed = 0.05 kilometers / 0.00833333333 hours
speed ≈ 6 km/h

Therefore, the boy's speed is approximately 6 km/h.
