from an elevation of 3.5m below the surface of the water, a northern bottlenose whale dives at a rate of 1.8m/s what is the whales depth after 4 min

To find the whale's depth after 4 minutes, we first need to determine how deep it can dive in that time.

First, let's convert 4 minutes to seconds:
4 minutes * 60 seconds/minute = 240 seconds

Next, we can use the formula for distance traveled: distance = rate * time. In this case, the rate is 1.8 m/s and the time is 240 seconds.

depth = 1.8 m/s * 240 s = 432 meters

Therefore, the whale's depth after 4 minutes is 432 meters.
