What does ‘? m/s = 25.2 km/h’ mean and how do you complete it?
x

Step-by-step explanation:

This is a unit conversion problem it seems.

Basically, you're trying to take 25.2 km/h and turn that into m/s.

Let's convert hours to seconds first, so you can sort of see what I mean:

So now we've done the first part of the equation, dealing with hours to seconds. See how we now have seconds in the denominator instead of hours? (Keep in mind, we don't want to multiply everything until the very very end!)

Now let's turn kilometers into meters (kilo- means thousand):

Now that we have that, let's multiply out the full equation to get our answer!

Therefore our answer is the nice and satisfying 7.
