Solve the following word problem. A fish is swimming at −10.8 meters, or 10.8 meters below sea level. Every 2 minutes it descends another 1.5 meters. How long will it take for the fish to reach a depth of −37.8 meters? Show your work and write a sentence to explain what your answer means.(4 points)
To solve the problem, we can set up an equation to represent the situation. Let "t" represent time in minutes, and "d" represent the depth in meters.
We know that the fish starts at a depth of -10.8 meters. After every 2 minutes, it descends another 1.5 meters.
So the equation that represents the situation is:
d = -10.8 - 1.5t
We need to find the time it takes for the fish to reach a depth of -37.8 meters, so we can set up the equation and solve for "t":
-37.8 = -10.8 - 1.5t
To isolate "t," we can first subtract -10.8 from both sides:
-37.8 + 10.8 = -1.5t
Simplifying:
-27 = -1.5t
Next, divide both sides by -1.5:
t = 27 / 1.5
t = 18
Therefore, it will take the fish 18 minutes to reach a depth of -37.8 meters.
Explanation:
The answer means that the fish, starting at a depth of -10.8 meters, descends at a rate of 1.5 meters every 2 minutes. After 18 minutes, the fish will have descended to a depth of -37.8 meters.
Can you simplify that sentence?
Sure, here is a simplified sentence:
The fish will take 18 minutes to reach a depth of -37.8 meters, descending at a rate of 1.5 meters every 2 minutes from its starting point at -10.8 meters.
