To find the water level at the end of summer, we need to add the initial water level (112.12 meters below sea level) to the additional drop during summer (213.21 meters below sea level).
112.1 + 213.21 = 325.31
Therefore, the water level at the end of summer is 325.31 meters below sea level.

The rainfall in a town was 2.3 inches above normal in June. In July, the rainfall was 1.2 inches below normal. What was the difference in rainfall between the months?
To find the difference in rainfall between the two months, we need to subtract the rainfall in July from the rainfall in June.
Rainfall in June: +2.3 inches
Rainfall in July: -1.2 inches
Difference = 2.3 - (-1.2) = 2.3 + 1.2 = 3.5 inches
Therefore, the difference in rainfall between June and July is 3.5 inches.
Rainfall in June: +2.3 inches
Rainfall in July: -1.2 inches
Difference = 2.3 - (-1.2) = 2.3 + 1.2 = 3.5 inches
Therefore, the difference in rainfall between June and July is 3.5 inches.
A submarine was at a depth of 106.3 feet below sea level. After 5 hours, the submarine was at 481.2 feet below sea level. How far did the submarine travel?
To find out how far the submarine traveled, we need to subtract the initial depth from the final depth.
Final depth: 481.2 feet below sea level
Initial depth: 106.3 feet below sea level
Distance traveled = Final depth - Initial depth
= 481.2 - 106.3
= 374.9 feet
Therefore, the submarine traveled a distance of 374.9 feet.
Final depth: 481.2 feet below sea level
Initial depth: 106.3 feet below sea level
Distance traveled = Final depth - Initial depth
= 481.2 - 106.3
= 374.9 feet
Therefore, the submarine traveled a distance of 374.9 feet.

The temperature on Monday is −4°C. On Tuesday, it is 13° colder. What is the temperature on Tuesday?
To find the temperature on Tuesday, we need to subtract 13 from the temperature on Monday.
Temperature on Monday: -4°C
Colder temperature on Tuesday: -4°C - 13°C = -17°C
Therefore, the temperature on Tuesday is -17°C.
Temperature on Monday: -4°C
Colder temperature on Tuesday: -4°C - 13°C = -17°C
Therefore, the temperature on Tuesday is -17°C.
Ping dove off a 10 meter platform. He reached a depth of 6 meters in the water. What was the change in height?
To find the change in height, we need to subtract the depth in the water from the height of the platform.
Height of the platform: 10 meters
Depth in the water: 6 meters
Change in height = Height of the platform - Depth in the water
= 10 meters - 6 meters
= 4 meters
Therefore, the change in height is 4 meters.
Height of the platform: 10 meters
Depth in the water: 6 meters
Change in height = Height of the platform - Depth in the water
= 10 meters - 6 meters
= 4 meters
Therefore, the change in height is 4 meters.
A parasail is 1/20 of a meter above the water. Then, after 10 minutes, the parasail is 1/50 of a meter above the water. What is the change in height?
To find the change in height, we need to subtract the initial height from the final height.
Initial height: 1/20 of a meter
Final height: 1/50 of a meter
Change in height = Final height - Initial height
= 1/50 - 1/20
= (1/50) * (4/4) - (1/20)
= 4/200 - 10/200
= -6/200
Therefore, the change in height is -6/200 of a meter, which can be simplified to -3/100 of a meter.
Initial height: 1/20 of a meter
Final height: 1/50 of a meter
Change in height = Final height - Initial height
= 1/50 - 1/20
= (1/50) * (4/4) - (1/20)
= 4/200 - 10/200
= -6/200
Therefore, the change in height is -6/200 of a meter, which can be simplified to -3/100 of a meter.
