Question

Ken leaves work 20 minutes late. He decides to make up time by taking the toll road instead of side streets. He can travel three times faster by taking the toll road. Create an equation to represent his total travel time, including wait time, where x is the number of minutes the drive was expected to take

Answer 1

`y = (1)/(3) x + 20`

Explanation:

We know that the toll road is 3 times faster than the side streets.

If 'x' represents the number of minutes she usually spend taking the side streets. The
`(1)/(3) x` represents the time she takes taking the toll road.

Also we need to create an equation to represent her total travel time, including wait time. Therefore, the equation is:

`y = (1)/(3) x + 20`

Therefore, the equation is:
`y = (1)/(3) x + 20`
