Answer :
Final answer:
The temperature of the room after 6 minutes of the air conditioner being switched on will be 21°C.
Explanation:
To find the temperature of the room after 6 minutes of the air conditioner being switched on, we need to subtract the cooling rate per minute from the initial temperature of the room. The air conditioner cools the room by 4°C per minute, so after 6 minutes, the temperature will decrease by 4°C multiplied by 6, which is 24°C.
Therefore, the temperature of the room after 6 minutes of the air conditioner being switched on will be 45°C - 24°C = 21°C.
To find the temperature of the room after 6 minutes, we can calculate the total temperature change and subtract it from the starting temperature. The air conditioner cools the room by 4° C each minute, so in 6 minutes, the temperature will drop by 4° C/min × 6 min = 24° C.
Therefore, the temperature of the room after 6 minutes will be 45° C - 24° C = 21° C.
