A diver jumps into the ocean from a boat. She starts at an elevation of 0 feet, and her elevation decreases by 60 feet every minute. What is her elevation after 5 minutes?

- 300 feet or 300 feet below sea level

Step-by-step explanation:

Starting elevation of diver = 0 feet

decrease of elevation in 1 minute = 60 feet

decrease of elevation in 1 * 5 minute = 60*5 feet = 300 feet

therefore

in five minutes diver loses 300 feet elevation

Elevation of diver after 5 minute = Starting elevation of diver - value of decrease of elevation of diver in five minutes

Elevation of diver after 5 minute = 0 feet - 300 feet = - 300 feet.

Therefore Elevation of diver after 5 minute is - 300 feet

i. e 300 feet below sea level as sea level elevation is taken as standard value of elevation of 0 feet.
