## Homework Statement

Driving along a crowded freeway, you notice that it takes a time t to go from one mile marker to the next. When you increase your speed by 5.0 mi/h, the time to go one mile decreases by 13 s. What was your original speed in mi/hr?

## Homework Equations

X (which in this case is 1 bc 1 mile)=VT

## The Attempt at a Solution

Ive tried countless times on paper

I know you convert the 13s into hr by dividing 13/3600

i know you do something with t-13

but im so lost.

please help!
