Question

The average temperature recorded in a city in 7 months is given below. Find the difference between the highest and the least temperatures.

• A. 5° F
• B. 4° F
• C. 33° F
• D. 28° F

Answer 1

The correct option is A 5° F


From the graph, we observe:
$\text{Average temperature in 1st month = 29° F}$
$\text{Average temperature in 2nd month = 31° F}$
$\text{Average temperature in 3rd month = 32° F}$
$\text{Average temperature in 4th month = 28° F}$
$\text{Average temperature in 5th month = 30° F}$
$\text{Average temperature in 6th month = 33° F}$
$\text{Average temperature in 7th month = 30° F}$



The graph shows that the least temperature is 28° F, and the highest temperature is 33° F.

So, the difference between the highest and least temperatures is
= 33° F – 28° F = 5° F
