Question

The graph above shows the height of the tide, in feet, above or below a baseline. Which of the following is closest to the difference, in feet,between the heights of the highest and lowest tides on July 13 at Bay Cove?

• A. $1.7$
• B. $1.9$
• C. $2.2$
• D. $2.5$
• E. $2.7$

Answer 1

The correct option is E $2.7$

From the given graph the highest tide height is $2.2$ ft. at $11:30$ a.m. and

the lowest tide height is $-0.5$ ft. at $6$ p.m.

Therefore, the difference between the heights of the highest and lowest tides is $2.2-(-0.5)=2.2+0.5=2.7$
