Hey there!!
After, the candle burning for 3 hours, the height is reduced to 17 inches.
After burning for 5 hours, the candles height is reduced to 15 inches
The height reduced = 17 - 15 = 2 inches.
Now, let's find out the height reduced by the flame in an hour.
It burnt for 3 hours at he start and then 2 hours after that, which gives us a total of 2 hours. In this span of two two hours, the candle height is reduced by 2 inches.
This states that, the candle would be reduced by 1 inch in an hour.
let's take the number of hours burnt = ' t '
Let's take the height of the candle after burning for t hours as ' h '
We know, the candle reduces by an inch every hour.
Which means, the inches reduced for burning for t hours = t
We know the candle burnt for 3 hours and we know the candle burns off an inch in a hour.
Through this, we know the original height o the candle = 17 + 3 inches
The original height of the candle = 20 inches.
Now, to find h , we subtract the inches reduced form the original height.
And we get the answer to our first question.
( i ) x = 20 - t
This is the equation
( ii ) The number of hours = 8
... x = 20 - 8
... x = 12 inches
Hope my answer helps!!
