Question

velocity of 18 km/hr is equivalent to
in m/sec​

Answer 1

When you write 18km/hr, it basically means the speed is 18 kilometres ….per hour, i.e, taking the quantities seperately ..

1 km = 1000 m

So, 18 km = 18*1000 m

Similarly, 1 hr = 60*60 seconds = 3600 seconds

Therefore, 18 km/hr = 18*1000 m / 3600 s

= 18000m/3600 s= 5m/s

(Or simply remember

Km/hr to m/s ……multiply the speed with 5/18

While m/s to km/hr….multiply the given speed with 18/5)

I hope you are understand my solution

Answer 2

Answer:

18×5/18

5m/s

Explanation:

18×1000/3600

1km=1000m

1hr=3600s

5m/s
