The Senior Class Car Wash Fundraiser: A Math Problem

The senior class is organizing a car wash to raise money for their school. They have a goal to wash a certain number of cars within a specific time frame. In this problem, we will help the senior class determine how many cars they can wash in one hour.

The senior class can wash about 35 cars in 5 hours. If they wash the same number of cars each hour, how many cars do they wash in 1 hour?

Step 1: Understand the Problem

To solve this problem, we need to understand the given information and what is being asked. The senior class can wash 35 cars in 5 hours. We need to find out how many cars they can wash in 1 hour.

Step 2: Identify the Key Information

The key information in this problem is:

The senior class can wash 35 cars in 5 hours.
They wash the same number of cars each hour.

Step 3: Use Division to Find the Answer

Since the senior class washes the same number of cars each hour, we can use division to find out how many cars they can wash in 1 hour. To do this, we will divide the total number of cars (35) by the number of hours (5).

Calculating the Number of Cars Washed per Hour

To calculate the number of cars washed per hour, we will use the following formula:

Number of cars washed per hour = Total number of cars ÷ Number of hours

Number of cars washed per hour = 35 ÷ 5

Number of cars washed per hour = 7

Therefore, the senior class can wash 7 cars in 1 hour.

This problem has a real-world application in the sense that it can help the senior class plan their car wash fundraiser more effectively. By knowing how many cars they can wash in 1 hour, they can estimate how much money they can raise and plan accordingly.

Here are some tips and variations to this problem:

What if the senior class wants to wash more cars in 1 hour? How can they increase their efficiency?
What if the senior class wants to wash cars for a longer period of time? How can they adjust their plan accordingly?
What if the senior class wants to raise more money? How can they increase their earnings?

The answer to this problem is 7 cars per hour.

This problem involves the following mathematical concepts:

Division
Fractions
Ratios

Here are some practice problems to help you reinforce your understanding of this concept:

If a group of friends can eat 24 sandwiches in 4 hours, how many sandwiches can they eat in 1 hour?
If a team of workers can build 120 houses in 6 months, how many houses can they build in 1 month?
If a company can produce 480 units in 8 hours, how many units can they produce in 1 hour?

In conclusion, this problem helps us understand how to use division to find the number of cars washed per hour. By applying this concept, the senior class can plan their car wash fundraiser more effectively and raise more money for their school.
