She is already 20 feet below sea level meaning she only needs 30 more feet to reach 50 ft below sea level.
tto figure out the amount of time it will take her to descend 30ft you multiply 30(distance) x 4(time)
tthe answer is 120
Step-by-step explanation:
Lets focus on what we know first. Natalie can pick 135 Berries in 15 minutes. Lets find out how many berries she can pick per minute.
In order to do so, We have to divide 135 by 15.
135/15=9
This means that Natalie can pick 9 berries per minute. Given that we want her to pick 486, we will need to divide that number by 9 berries to find out how many minutes it will take to get her to that number of berries.
486/9=54
This means that it will take Natalie 54 minutes in order to pick 486 berries.
