Question

A town has accumulated 2 inches of snow, and the snow depth in increasing by 6 inches every hour. A nearby town has accumulated 9 inches, and the depth is increasing by 3 inches every hour. In about how many hours will the snowfall of the town s be equal? Round our answer to the nearest tenth, 

Answer 1

Town A starts with 2in and has a rate of accumulation of 6in every 1 hour
Town B starts with 9in and has a rate of accumulation of 3in every 1 hour

If X is number of hours then:

2+ 6X= 9+3X
6x-3x=9-2
3x=7
X=7/3 is about 2 hours
