Can you rewrite this please? "To determine how long it will take for the fish to reach a depth of (-37.8) meters, we start by noting that the fish is initially at (-10.8) meters. The fish descends (1.5) meters every (2) minutes. The total distance the fish needs to descend is (-27) meters, calculated by subtracting (-10.8) from (-37.8). To find the number of (2)-minute intervals required to descend this distance, we divide (27) by (1.5), resulting in (18) intervals. Since each interval is (2) minutes, the total time taken is (18 \times 2 = 36) minutes. Therefore, it will take the fish (36) minutes to reach a depth of (-37.8) meters."

To calculate the time it will take for the fish to reach a depth of -37.8 meters, we start by recognizing that the fish is currently at a depth of -10.8 meters. It descends at a rate of 1.5 meters every 2 minutes. The fish needs to descend a total of 27 meters, which we find by subtracting -10.8 from -37.8. To determine the number of 2-minute intervals needed to cover this distance, we divide 27 by 1.5, yielding 18 intervals. Since each interval lasts 2 minutes, the total time required is 18 multiplied by 2, which equals 36 minutes. Thus, it will take the fish 36 minutes to reach a depth of -37.8 meters.
