Hey.
Here is the answer.
v = 18 m/s
as, 1 km has 1000 m.
so, 1 m = 0.001 km
also, 1 hr = 3600 sec
so, 1sec = 1/3600 hr
So, v = 18×0.001 km / (/1/3600 hr)
= 18×3600/1000 = 64.8 km/h
Thanks.

velocity = 18 m/sec.
1 meter = 0.001 Km
1 sec. = 1/3600 hr
velocity = 18 x (0.001 /1 / 3600)
velocity = 18 x 3.6
velocity = 18 x (18/5)
velocity = 64.8 Km/hr
and if u wanna change Km/hr to m/sec the multiply by 5/18 and m/sec to km/hr then now u know multiply by 18/5.
i hope it will help you
