Gennadij [26K]

Answer:

240 - 5x and the candle will be at 0 mm in 48 seconds

Step-by-step explanation:

<u>Step 1:  Convert words into an expression</u>

<em>x = 48</em>

Answer:  240 - 5x and the candle will be at 0 mm in 48 seconds

Graph Below:  (0, 240) shows the initial start and (48, 0) shows the ending point
