Sorry, but this isn't that sort of site.

But if you'd like to learn how to do this on your own....

First, you'll need to learn what

variables are and how to "

translate" relationships from English statements into algebraic expressions and equations. Once you have learned the basics, you may want to study how to set up and solve "

distance" word problems.

At that point, you should be able to complete the following:

+--------+-----+--------+---+

|########| d = r * t |

+--------+-----+--------+---+

| faster | | r | 3 |

+--------+-----+--------+---+

| slower | | r + 10 | 3 |

+--------+-----+--------+---+

Use the "distance" equation explained in the lesson to create expressions for the distance each car covered. Then add their individual distances and set the sum equal to the given total.

Solve the linear equation for the value of the variable. Back-solve for the required information.

If, after studying the lessons, you get stuck in working the exercise, please reply with a clear listing of your steps and reasoning so far. Thank you!
