Mark the number of hours with snowfall as x. Describe the snowfalls in both towns in terms of x to make an equation.
45
We are told that two towns have accumulated different amounts of snow. In Town 1 there is already 5 inches of snow and its depth is increasing by 3 12 inches every hour. In Town 2 there is 6 inches and the depth is increasing by 2 14 inches every hour. We want to find the number of hours after which the snowfalls in two towns will be equal. Let's start with defining x.
x - the number of hours with snowfall
Let's now express the snowfalls of both towns in terms of x. In Town 1 there is 3 12 inches of snow every hour plus 5 inches. Therefore, the snowfall will be the number of hours x multiplied by 3 12 plus 5. In Town 2 there is 2 14 inch of snow every hour plus 6 inches, so the snowfall will be the number of hours x multiplied by 2 14 plus 6.

The snow will have to fall for 45 hours for the snowfall to be equal in both towns.
