Question

A 5-inch candle burns down in 10 hours. After how many hours will it have burned 7 1/4 inches? Use the drop down menu to state your answer as a decimal, mixed number, or improper fraction.

Answer 1

Answer:

14.5

Explanation:

Inches = k * (hours)

$\frac{Inches}{Hours}=k\\\\\frac{5}{10}=k \\\\0.5=k$

$i=0.5 *h\\\\7\frac {1}{4} =0.5*h\\\\7.25=0.25*h\\\\\frac{7.25}{0.5} =h\\\\14.5=h$

Hope this helps!
