What does ‘? m/s = 25.2 km/h’ mean and how do you complete it? Thanks 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.
Answer:
7

Answer:
Kevin should do 15 shock replacements and 6 brake replacements every week to maximize his weekly income.
Step-by-step explanation:
Both jobs take the same amount of time to complete (2 hours), therefore, in order to maximize his income, Kevin should prioritize the job that gives him the greatest income, which is replacing shocks.
If each job takes 2 hours and he works at most 42 hours per week, Kevin can complete 21 jobs per week. He should aim to do as little break replacements as possible and as many shock replacements as possible to maximize income.
If he completes at least 6 break replacements, the remaining jobs should all be shock replacements:
Kevin should do 15 shock replacements and 6 brake replacements every week to maximize his weekly income.
