Question

A car is moving with a speed of 100 km/h. Calculate its speed in m/s.

Answer 1

Answer:

100*1000/3600

100*5/18

500/18 m/s

Answer 2

$\huge\underline\mathtt\pink{Answer}$

$speed \: of \: car \: in \: {ms}^{ - 1}$

$= \frac{100km}{hr}$

$= \frac{100 \times 1000}{1 \times 60 \times 60}$

$= \frac{1000}{36}$

$= 27.777$

$= 27.8 {ms}^{ - 1}$
