The temperature outside is dropping at 3°/h. Given that the temperature at noon was 0°, what would the temperature at 1 PM at 2 PM at 3 PM and 6 PM what was the temperature T hours afternoon

Change in temp = - 3/h

From noon to 1pm, 1 hour has passed, so temp = 0 degrees - 3 degrees = - 3 degrees

From 1pm to 2pm, 1 hour has passed, so temp = - 3 degrees - 3 degrees = - 6 degrees

From 2pm to 3pm, 1 hour has passed, so temp = - 6 degrees - 3 degrees = - 9 degrees

From 3pm to 6pm, 3 hours have passed, so temp

= - 9 degrees - (3 * 3 degrees)

= - 9 degrees - 9 degrees = - 18 degrees
