Usually the problem is the driving rather than the work. Your kid puts in two hours and the household absorbs six, and nobody has counted it out loud. Naming your availability as a fixed constraint turns it into a business problem your kid can solve with density, batching, or a higher price, and every one of those is a better lesson than being told to do less.
Count the real hours before deciding anything, because the number is usually not what anyone assumed. The job takes ninety minutes. The trip there, the wait, the trip back, the second trip when something was forgotten, and the run to the hardware store push the household cost past four hours. Your kid experiences the ninety minutes and you experience the four, which is why you are the only person in the house who thinks this is getting out of hand.
Say it plainly rather than carrying it. Quiet resentment about logistics is what ends more of these than any customer ever does, and it tends to come out sideways as a comment about effort or attitude.
Then hand it over as a constraint instead of a complaint. I can do two trips on Saturday morning, between eight and eleven. That is not a punishment, it is exactly the kind of limit every real business operates inside, and working out how to get more done within a fixed window is a genuinely useful problem.
There are three ways out of it and your kid can find all three.
Density. Customers who are close together turn four trips into one. This is the single biggest lever and most kids have never considered it, because they think of customers as people rather than as points on a map. Ten houses on one street is a different business from ten houses across a town.
Batching. Everything on one day rather than scattered across five evenings. Harder work, far less overhead, and it protects the rest of the week for everybody.
Price. Fewer jobs at a higher number earns the same money in less time. A kid who is turning down work because there are no slots left does not have a scheduling problem, they have a pricing signal.
One thing worth checking honestly before any of it. Is the business taking over the weekend, or have you taken over the business? If the six hours are yours because you are driving, waiting, helping, and finishing, the load is real and the cause might be how much of it you have absorbed rather than how many customers there are.
