Question

Adam ran 21.5 miles less than Jacob. If Adam ran 17.5 miles. How many miles did Jacob run? Write an equation and solve.

Answer 1

39 miles

Explanation:

We can start by using algebra to represent the problem in equation form. Let j be the number of miles Jacob ran.

From the information given, we know that:
Adam ran 21.5 miles less than Jacob.
Adam ran 17.5 miles.

We can use these two pieces of information to set up the following equation:
j = 17.5 + 21.5

Now we can solve for j by adding 21.5 to both sides:
j = 39

So Jacob ran 39 miles.
