Question

Express the speed of 18/5 kmph in m/ s

Answer 1

18/5 km/h = 18/5 x 5/18 = 1

Answer 2

we have to express the speed of 18 km/h in m/s .

we know, 1 kilometre = 1000 meters
and 1 hour = 3600 seconds

so, 1 km/h = 1000m/3600 sec = 5/18 m/sec

hence we get , 1km/h = 5/18 m/s

so, 18/5 km/h = 18/5 × 5/18 = 1 m/s

hence, the speed of 18/5 km/h in m/s = 1m/s
