To find how long it will take for the fish to reach a depth of -37.8 m, we need to determine how many times it will descend by 1.5 m before reaching that depth.
The difference in depth between the starting point and the desired depth is -37.8 m - (-10.8 m) = -37.8 m + 10.8 m = -27 m.
Since the fish descends by 1.5 m every two minutes, the number of descents it will make is -27 m / 1.5 m = -18.
Therefore, it will take the fish 18 * 2 = 36 minutes to reach a depth of -37.8 m.
This means that the fish will take 36 minutes to swim 10.8 m below sea level to a depth of -37.8 m.
Solve the following word problem a fish is swimming at -10.8 m or 10.8 m below sea level every two minutes it descends another one and a half meters. How long will it take for the fish to reach a depth of -37.8 m show your work and write a sentence to explain what your answer means.
