Question

a boy starts running from his house with a uniform speed and takes 1 hour to reach the playground. If the distance between his house and the playground is 3.6km , calculate his speed in km\h ,m\s and cm/s

Answer 1

3.6×1000/1×60×60. Or 3.6×5/18 or.
0.2×5= 1m/s or 100cm/s

Answer 2

TIME- 1hr.

DIST.= 3.6 km.

》》》》》》》

Therefore, in km/hr= 3.6 km/hr

because, as it is told to convert into km/hr and here 3.6 km is already given. So, by the condition to it will be 3.6 km/hr.

Now,

m/s = 3.6 × 1000/ 3600 m/s

then, the ans by calculating is = 1.0 m/s.

so, it will be only 1m/s.

So as to convert it to cm/s,

then, cm/s= 3.6 × 1000/3600

= 36 × 1000 × 10/ 3600

= 100 cm/s.
