Answer: The date in which the water level will not exceed 18ft is August 12 ( 6 weeks after July 1)
Step-by-step explanation:
Given:
Initial water level = 22ft
Final water level = 18ft
Total water level change = 22-18 = 4ft
Rate of change of water level = 2/3 ft/week
Using the formula;
Total change = rate × time
Time = total change/rate
Substituting the values of the rate and total water level change.
Time = 4/(2/3) week = 4 × 3 ÷2 = 6weeks.
From July 1 + 6 weeks = August 12
The date in which the water level will not exceed 18ft is August 12 ( 6 weeks after July 1)
