Question

36 km/hr can be represented as:

• A. 10 m/s
• B. 20 m/s
• C. 30 m/s
• D. 40 m/s

Answer 1

The correct option is A

10 m/s

The S.I. unit of speed is meter per second. So by converting 36 km/h to S.I. units we get:

$36\times \frac{1000m}{3600s}$

=$\frac{1000}{100}=10m/s$

or we can get it by multiplying speed in km/h by $\frac{5}{18}$

Speed $=36\times \frac{5}{18}$ = 10 m/s
