The weather report says the temperature is 20°c and will drop 5°c per hour for the next 6 hours.
Temperature drops by 5°c per hour
So we find the temperature after 6 hours
In 1 hour temperature drops= 5°c
So in 6 hours = 6* 5 = 30°c
In 6 hours , temperature drops by 30°c
the actual temperature is 20°c. after 6 hours the temperature becomes
20°c - 30°c= -10°c
So, after 6 hours the temperature will be -10°c
Daryl plans to be gone for at least 6 hours. so its 6 hours or more than 6 hours
In 6 hours or more than 6 hours , the temperature will drop less than -10°c.
So, Daryl should move his plant to a warmer location before leaving
