Answer

Explanation:

Step1: Subtract cost of safety - course from budget

Let the budget be $280$ and cost of safety - course be $10$. So the remaining money for boat rental is $280 - 10=270$.

Step2: Divide remaining money by hourly - rental rate

The boat rental rate is $60$ per hour. Let the number of hours be $h$. Then $h=\frac{270}{60}=4.5$. But the boat rental is available only for whole hours, so the maximum whole - number of hours is $4$.
