The temperature of the furnace is 1200 and cool at a rate of 15 per minute the temperature of another furnace is 900 and is heat

Hunter-Best [27]

Answer:

After 15 minutes, the temperature of both the furnaces will be same.

Step-by-step explanation:

Let $x$ be the minutes when the temperature of both becomes same.

Now, as per question:

Temperature of the furnace after $x$ minutes that is cooling at the rate of 15 degree per minute is given as:

$T=1200-15x$

Temperature of the furnace after $x$ minutes that is heating at the rate of 5 degree per minute is given as:

$T=900+5x$

Now, equating both the temperatures, we get

$1200-15x=900+5x\\1200-900=15x+5x\\300=20x\\x=\frac{300}{20}=15\ min$

Therefore, after 15 minutes, the temperature of both the furnaces will be same.
