Question

In Utah, there are 5 inches of snow at 6:00AM. The amount of snow increases 3 inches each hour until 9:00am. Then, the snow starts to melt and decreases by 1 inch per hour until 11:00am.

How many inches of snow are there at 11:00am?

Answer 1

Explanation:

6 :00 AM to 9:00 AM=9-6=3 hours

9:00 AM to 11:00 AM=11-9=2 hours

snow at 9:00 AM=5+3(3)=5+9= 14 inch

snow at 11:00 AM =14-2(1)=14-2=12 inch
