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 10 ​inches, and the depth is increasing by 2 inches every hour. In about how many hours will the snowfall of the towns be​ equal?

Answer 1

A=2+6t, b=10+2t

a=b when

2+6t=10+2t  subtract 2t from both sides

2+4t=10  subtract 2 from both sides

4t=8  divide both sides by 4

t=2

So they will have the same snowfall in two hours.
