Question

now look at these two scenarios. match the scenarios to the equations. a dolphin was diving at a rate of 3 meters per second. how long will it take for the dolphin to get from the surface of the ocean to an elevation of -9 meters at that rate? a pelican dove below the surface of the ocean. after 3 minutes, it was 9 meters below the surface. at what rate was it diving? 3x = -9 -3x = -9

Explanation:

Step1: Analyze Dolphin Scenario

Let \(x\) = time (seconds). Rate = 3 m/s downward (negative elevation change: \(3x = -9\)).

Step2: Analyze Pelican Scenario

Let \(x\) = rate (m/min). Time = 3 min, elevation = -9 m: \(-3x = -9\) (negative rate for downward).

Answer:

Dolphin scenario ↔ \(3x = -9\); Pelican scenario ↔ \(-3x = -9\)
