Question 14469
ok....let's see....we can solve this with an equation as you probably already figured out

you have two people so you know to equation will be the sum of two terms equal 300.

There are two drivers: Driver A and Driver B

Let x represent to number of miles Driver A drove.
Driver b drove 3 times as much as Driver A.

So that would be...x+3x=300

Now, let's solve:

x+3x=300
4x=300
x=300/4
x=75

Now you have the miles of Driver A, you cna find out the miles of Driver B.

Driver b=3x
        =3 x 75
        =225

Therefore, Driver A drove 75 miles and Driver B drove 225 miles.

(let's check to be sure)
225+75=300....yay!
