Let's start:
Step 1: Adrian's initial position. This is given as 5 feet below sea level. We'll keep this in mind.
Step 2: Find Adrian's diving rate. The problem states that he dives at a rate of 5 3/8 feet per minute. This means that every minute Adrian is diving, he goes 5 3/8 feet deeper below sea level.
Step 3: Calculate how deep Adrian dives for the given minutes. We do this by multiplying the diving rate (5 3/8 feet per minute) by the number of minutes.
Step 4: Determine the total depth. To do this we add the initial depth (5 feet) to the depth that Adrian dived.
So, if we want to know the total depth after, let's say, 20 minutes of diving, here's what we would do:
1. Divide the fraction 3/8 to convert it to decimal, which gives 0.375.
2. Add this to the 5 feet to get the diving rate per minute, so 5 + 0.375 = 5.375 feet per minute.
3. Multiply this rate by 20 minutes, so 5.375 * 20 = 107.5 feet.
4. Add the initial depth of 5 feet to this, so 107.5 + 5 = 112.5 feet.
That means, after 20 minutes of diving, Adrian will be 112.5 feet below sea level.
Remember, this is explained for 20 minutes. You can replace this 20 minutes with any number of minutes you wish to explore how far Adrian would have dived over that time.
