36 km/h is same as
(a) 36 m/s
(b) 3.6 m/s
(c) 10 m/s
(d) 0.36 m/s

(c) 10 m/s

Given: 36 km/h
Converting 36 km to m:
1km = 1000 m​
36 km = 36 $\times$ 1000 = 36000 m
Also, 1h = 60 min
1 min = 60 s

1 h = 60 $\times$ 60 = 3600 s

Hence,​

$\frac{36000}{3600}\mathrm{m}/\mathrm{s}=10\mathrm{m}/\mathrm{s}$
