Answer 1

To find the depth after 4 minutes, we need to know the distance the whale travels during that time. We can use the formula:

distance = rate * time

So, the distance the whale travels in 4 minutes is:

distance = 1.8 m/s * 4 min = 7.2 m

Since the whale started at an elevation of 3.5 m below the surface, we need to subtract this distance from the initial depth:

depth = -3.5 m - 7.2 m = -10.7 m

Therefore, the whale's depth after 4 minutes is negative 10.7 meters. The correct answer is negative 10.7 meters.
