Answer 2

Explanation:

Let's set up a proportion to solve. Use the following setup:

We know that it takes Oliver 4 hours to drive 278 miles.

We don't know how long it takes him to drive 139 miles. Therefore, we use the variable x for hours, because it is unknown.

We are solving for x, the hours it takes him to drive 139 miles. The variable must be isolated. It is being divided by 139 and the inverse of division is multiplication. Multiply both sides of the equation by 139.

It takes Oliver 2 hours to drive 139 miles.
