Seems easy but I need help. if the speed of x meters per sec

if the speed of x meters per second is equivalent to the speed of y kilometers per hour, what is y in terms of x? Answer 18x/5

I'm sure this isn't hard but I'm bleary eyed and could use a little help on this one.
Thanks!

Start with 1km/hour

The aim is to convert this to m/s

1km = 1000metres

1Hour = 60mins = 60x60 secs

So 1 km/hr = 1000/(60x60) metres/sec

Simplifying = 1km/hr = 5/18 metres/sec
