Question

A town has accumulated 2 inches of​ snow, and the snow depth is increasing by 6 inches every hour. A nearby town has accumulated 7 ​inches, and the depth is increasing by 3 inches every hour. In about how many hours will the snowfall of the towns be​ equal?

Answer 1

You basically make an equation out of this and set the two expressions equal to each other.

Let x equal the number of hours where the snowfall will be equal in both towns.

In town one, the amount of snowfall can be written as 2+6x. In town two, the amount of snowfall can be written as 7+3x.

So to find when they will be equal, set them equal and solve:

2+6x=7+3x
3x=5
x=5/3 or 1 2/3 hours. In minutes, this is 100 minutes.
