65.0 (km/hour)
= 65 * 1000 m/h
= 65 * 1000/60 m/min
= 65 * 1000/(60 * 60) m/s
= 18.056 m/s
= 18 m/s to nearest m

65.0 km/hour can be written as:
(65*km) / (1*hr)
and we need to know some basic conversions:
1 km = 1000 m = 1000*m
1 hr = 60 min = 60*min
1 min = 60 s = 60*s
subsitute:
(65*km) / (1*hr)
(65* 1000m) / (60*min)
(65000*m) / (60*60*s)
65000*m / 3600*s
650*m / 368*s
325*m / 18*s
(325/18)*(m/s)
~= 18.05555.... m/s

Is it meter per second?
I'll assume it is.
1 km = 1,000 meters
1 hour = 3600 seconds
so we write the ratio
65*1000 meters/3600 seconds = 65000/3600 m/s
650/36 = 18.056 m/s

How many meters in kilometre? 1000 (numerator on top)
How many seconds in hour? 3600 (denominator on bottom)
65.0 times 1000 is 65000.
65000 divided by 3600 is your answer.
Which is: 18.055555555555555555555555555556

multiply by 5/18. so 65(5/18) or about 18.1 m/s
have yourself a good day
