A fish is swimming at -10.8 m, or 10.8 m below sea level. Every two minutes it the seats another one. 5 m how long will it take for the fish to reach a deep of -37.8 m.

Answer 1

To determine how long it will take for the fish to reach a depth of -37.8 m, we need to find out how many times the fish needs to descend by 5 m.

First, we calculate the difference between the initial depth (-10.8 m) and the target depth (-37.8 m): -37.8 m - (-10.8 m) = -37.8 m + 10.8 m = -27 m.

Since the fish descends by 5 m every 2 minutes, we divide the difference in depth by the descent rate: -27 m / 5 m = 5.4.

This means that the fish needs to descend 5.4 times to reach a depth of -37.8 m.

Given that it takes 2 minutes for the fish to descend once, we multiply the number of descents needed by the time it takes for each descent: 5.4 x 2 = 10.8.

Therefore, it will take the fish approximately 10.8 minutes to reach a depth of -37.8 m.
