Question

Yolanda measures the depth of the water in a reservoir. In one week, the depth changes from 2,366.74 ft to 2,354.63 ft. What rational number represents the average change in depth each day? Show your work.

Answer 1

To find the average change in depth each day, you need to divide the total change in depth over the course of one week by the number of days in a week.

Total change in depth = Initial depth - Final depth

Total change in depth = 2,366.74 ft - 2,354.63 ft = 12.11 ft

Number of days in a week = 7 days

Now, divide the total change in depth by the number of days:

Average change in depth each day = Total change in depth / Number of days

Average change in depth each day = 12.11 ft / 7 days ≈ 1.73 ft per day

So, the rational number that represents the average change in depth each day is approximately 1.73 feet per day.

Hope this helps
