To solve this word problem, we can use the concept of distance traveled over time.
The fish is initially swimming at a depth of −10.8 meters and descends another 1.5 meters every 2 minutes. We want to find out how long it will take for the fish to reach a depth of −37.8 meters.
Let's assume that it takes t minutes for the fish to reach a depth of −37.8 meters.
Now, let's calculate the distance traveled by the fish in t minutes:
Distance traveled = initial depth + additional distance traveled
Distance traveled = −10.8 meters + (−1.5 meters/2 minutes) * t minutes
According to the problem, we want to find out when the depth reaches −37.8 meters. So we set up the equation:
−10.8 meters + (−1.5 meters/2 minutes) * t minutes = −37.8 meters
Simplifying this equation:
−10.8 meters - (1.5 meters/2 minutes) * t minutes = −37.8 meters
Next, we can solve for t by isolating the variable:
(−1.5 meters/2 minutes) * t minutes = −37.8 meters + 10.8 meters
(−1.5/2) * t = −37.8 + 10.8
−0.75t = −27
Dividing both sides by −0.75:
t = −27 / −0.75
t = 36
Therefore, the fish will take 36 minutes to reach a depth of −37.8 meters.
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? PLEASE HELPP
