Question

covers 54 kilometre in one hour what is its speed in metre per second​

Answer 1

Answer:

15m/s

Step-by-step explanation:

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
