b. Jasmine saw 5 sea cucumbers in 9 minutes.

c. Robert saw 8 jellyfish in minutes.

d. Shilpa saw 4 pencil urchins in minutes.

Answer 1

The question is incomplete. I don't know in how many minutes Robert and Shilpa spotted their sea life.

Answer 2

@Faman--> Need the minutes on Robert and Shilpa

Robert saw 8 jellyfish in??? minutes.

d. Shilpa saw 4 pencil urchins in??? minutes.

Answer 3

Well if the question is like this lance saw sea life at the fastest rate.Because he took less time to see it.The lesser the time the higher the rate.

Answer 4

@Faman39 Need data here now

Answer 5

Four friends went scuba diving. According to the following statements, who spotted sea life at the fastest rate?

a. Lance saw 3 reef sharks in 5 minutes.

b. Jasmine saw 5 sea cucumbers in 9 minutes.

c. Robert saw 8 jellyfish in 15 minutes.

d. Shilpa saw 4 pencil urchins in 10 minutes.

Answer 6

Divide the amount of sea life by the amount of minutes. The one that is the highest number will turn out to be the fastest rate.

3/5 = ? reef sharks/ min

5/9 = ? Sea cucumbers/ min

8/(missing data) = ? jellyfish/ min

4/(missing data) = ? pencil urchins/min

Answer 7

Okay then the last two would be 8/15 and 4/10

Answer 8

Let me know what your answers were and what you think is the fastest rate based upon your answers.

Answer 9

B

Answer 10

?

Answer 11

Sec, I'll put them all in.

Answer 12

ok, no prob

Answer 13

A.) 0.6
B.) 0.56
C.) 0.53
D.)0.4

(I just divided the amount of sea life by the number of minutes to get these decimal answers)

What is the largest number? What does this number represent?

Answer 14

i put that, its up there

Answer 15

@Directrix scroll up, he gave them.

Answer 16

@Faman39 what do you think the answer to my questions are?

A.) 0.6
B.) 0.56
C.) 0.53
D.)0.4

(I just divided the amount of sea life by the number of minutes to get these decimal answers)

What is the largest number? What does this number represent?

Answer 17

i think, it should be the second one

Answer 18

What is the largest number?

Answer 19

0.56?

Answer 20

0.6

Answer 21

0.56 + 0.04 = 0.6

Therefore, 0.6 is greater than 0.56.

Answer 22

This number represents the rate at which the friend sees reef sharks. 0.6 reef sharks per minute.

Or you can say 3/5 reef sharks per minute.

Answer 23

a. Lance saw 3 reef sharks in 5 minutes. --> 3/5 minutes per shark

b. Jasmine saw 5 sea cucumbers in 9 minutes. --> 5/9 minute per cucumber

c. Robert saw 8 jellyfish in 15 minutes. ---> 8/15 minutes per jellyfish

d. Shilpa saw 4 pencil urchins in 10 minutes. ---> 4/10 minutes per urchin

Now, what about this?

Answer 24

Or, is it:
a. Lance saw 3 reef sharks in 5 minutes. --> 3/5 sharks per minute

b. Jasmine saw 5 sea cucumbers in 9 minutes. --> 5/9 cucumbers per minute

c. Robert saw 8 jellyfish in 15 minutes. ---> 8/15 jellyfish per minute

d. Shilpa saw 4 pencil urchins in 10 minutes. ---> 4/10 urchins per minute

Answer 25

My working answer:

a. Lance saw 3 reef sharks in 5 minutes. --> Fastest Rate

Answer 26

Answer: Lance

Guest Solution by TFP:

Assuming that the viewing rate remains constant for 45 minutes:

If you do a common denominator of 45 minutes, you get:

Lance 3/5 = 27/45 --->
Jasmine 5/9 = 25/45
Robert 8/15 = 24/25
Shilpa 4/10 = 18/45
