Answer:
T = 70 - m/3
Step-by-step explanation:
Hi,
Let the temperature of the room be represented by T
Given that Initial temperature was 70°F
If a window is open, temperature of the room falls 5°F for every
15 minutes
So, for 1 min, Temperature falls by 5/15 = 1/3°F
After m minutes of window being open, temperature falls by
m* 1/3 = m/3° F
Hence, temperature of the room after m minutes of window been
open will be
T = 70 - (m/3)
Hope, it helps !
