Answer:
8 hours
Step-by-step explanation:
Let's first find how many inches the candle would have burned in 1 hour.
6 in:12 hours
x: 1 hour
We can divide 12 by 12 to get 1. This means we need to divide 6 by 12 to get x
x=1/2 inches
1/2 inches:1 hour
4 inches: x hours
We divide 4 by 1/2 to get 8. 1/2*8=4. This means...
x=1 hour*8=8 hours
