Question

water evaporates from a pond at a rate of 0.05 inches per hour. what is the change in inches in the water level of the pond after 24 hours? 1.2 inches -1.2 inches -12 inches 12 inches

Explanation:

Step1: Identify the evaporation rate and time

Evaporation rate = 0.05 inches per hour, time = 24 hours.

Step2: Calculate the total change in water level

The change in water level = evaporation rate×time, so $0.05\times24 = 1.2$ inches. But since it is evaporation (water level is decreasing), the change is - 1.2 inches.

Answer:

B. -1.2 inches
