25km/hr = 6.94m/sec
1km = 1000m, 1hr = 3600 secs
25km/hr x 1000m/1km x 1hr/3600sec = 6.944m/sec........

IT's simple Whenever there is need to convert from m/s to km/hr, we should multiply the values of m/s by 18/5 because there is 1/1000 km in 1 meter and 1/3600 hr in 1 second. So when the are divided answer is 18/5. The value is : 0.25m/s => (25/100)* (18/5) => 9/10 km/hr

Write down the units as you convert. I find it easier to keep with the conversion
25 (km/hr) * 1000 (m/km) / 3600 (sec/hr)
Reduce the numbers 25*1000/3600=6.94
Now
(km/hr) * (m/km) / (sec/hr)
Simplify
(km/hr) * (m/km) * (hr/sec)
You can see the units that cancel and (m/sec) remains.
This ensures that one set up the conversion correctly.

25 km/h = 25* (1000m)/(3600seg) = 250/36 m/seg = 6.944 m/s
