How do you determine how to set it up? I'm confused.

**Kay**, Monday, September 17, 2007 at 6:41pmlet's say the second speed = x

look at how the units present in the q give you a clue about how to solve the equation:

*mph = miles per hour.

*hours.

*miles.

miles PER hour = miles/hour

MPH = miles/hour is the conversion

1. the first machine: 60mph and 7.2hours. how do you solve for miles?

miles=mph*hours

2. the second machine: set this one up, but use variable (x) for the speed (mph).

hope this helps
