Question

54 km/ hr = how much m/s​

Answer 1

Firstly, We know that

1 Kilometer(Km) = 1000 Meter(m)

Secondly,

1 Hour(H) = 60 Minutes

&

1 Minute = 60 Seconds

Therefore,

1 Hour(H) = 60 x 60 Seconds(s) = 3,600 Seconds(s)

Hence,

1 Km/H = 1000/ 3,600 m/s = 5/18 m/s

Therefore,

54 Km/H = 54 x (5/18) = 15 m/s

Answer 2

Answer:

simple method :-

$kmph \: \times \frac{5}{18} = m \: p \: s$

therefore,

$54 \times \frac{5}{18}$

$= 15 \: \: m \: p \: s \:$

therefore, 15 m/s .
