Linear Equations with Time - Basic Math

We can write a linear equation from the information given in the question:

Since Sarah has 15 problems, she has 3 sets of 5 problems.

Substituting that information gives the following equation:

Now, the question asks at what time Sarah will finish her algebra problems.

Now, add that to 3 pm.

To solve this problem, you need to create a linear equation. First, you know that it takes two hours total for Francine to get to school. Two hours can also been translated into a hundred and twenty minutes. Second, you know that it only takes her twenty minutes to get ready. Your variable is the time it takes her to get to school.

So:

Therefore, .

Now we convert this back into hours and minutes.

Since 60 minutes is 1 hour it takes Francine an hour and fourty minutes to get to school.

Let represent the number of hours each jogger runs. We know that the first jogger is running at a rate of 4 miles per hour; since , we therefore know that the first jogger runs a distance of .

By the same logic, we know that the second jogger runs a distance of .

Since we are looking for the point at which the joggers meet up after running from opposite directions, we know that together they will have covered a total of 10 miles. Therefore:

Simplifying the equation:

Let equal the number of hours it takes Daisy to plant strawberry plants.

Given that she can plant 10 strawberry plants in an hour, Daisy can plant strawberry plants in an hour.

If she wants to plant 70 strawberry plants, then she will plant strawberry plants.

Dividing both sides by 10, we find that Daisy will take to plan 70 strawberry plants.

Let equal the total number of hours Jimmy works in a given day. If he earns $30 per hour, then is the total amount of money Jimmy earns in a day. Given that he earned $270 on a given day:

Dividing both sides by 30:
