Question

Speed v = 54 km h-1
54x1000 m
15 m s-1
3600 s
what will be the answer to get fifteen​

Answer 1

Answer: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
