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.
From an elevation of 3.5 m below the surface of the water, a northern bottlenose whale dives at a rate of 1.8 m/s. What is the whale’s depth after 4 min?
