At 7:00 pm the temperature was 40F. If the temperature dropped steadily at a rate of 6 degrees per hour, what was the temperature at 11:00 pm? The answer with explanation please
Answers
Answer:
16F
Step-by-step explanation:
11-7=4
There were 6 degrees per hour falling and there were 4 hours.
Then it will be 6x4=24
Thus, 40-24= 16F
The temperature at 11:00 pm is 16F
Given :
- At 7:00 pm the temperature was 40F.
- The temperature dropped steadily at a rate of 6 degrees per hour
To find :
The temperature at 11:00 pm
Solution :
Step 1 of 2 :
Calculate decrease in temperature
Here it is given that at 7:00 pm the temperature was 40F.
The temperature dropped steadily at a rate of 6 degrees per hour
Total time
= 11:00 pm - 7:00 pm
= 4 hours
∴ Total decrease in temperature
= 4 × 6 degrees
= 24 degrees
Step 2 of 2 :
Calculate the temperature at 11:00 pm
The temperature at 11:00 pm
= (40 - 24)F
= 16F
