I set it up like this: 45t+55t=2.5 hours

I got she lives 100 miles but I don't know for sure if I did it right. If someone could check my work I would love it. Thanks in advance.

**Marth**, Sunday, August 16, 2009 at 9:48pmI do not get 100 miles.

Here is a better way to set up the equation:

let d = the distance between the two houses.

The total time is 4 hours. The time spent traveling can be found by manipulating V = d/t

t = d/V

So the time is the displacement divided by the velocity.

45/d + 55/d + 1.5 = 4

d = ?
