Answer: B

Step-by-step explanation:

1.) Calculate the percentage that blue balls make of the bag. First, add the balls together.

5 + 4 + 3 = 12

2.) Divide 100 / 12.

100 / 12 ≈ 8.3

3.) Multiply 8.3 by the number of blue balls.

8.3 * 5 ≈ 40

4.) Convert the percentage to decimal form.

40 / 100 = 0.4

notsponge [240]

Answer:

It takes the Dolphin 2 hours for swimming 40 miles. The penguin takes 8 hours and the swordfish will take 2/3 of an hour, which is 40 minutes to travel 40 miles.

Step-by-step explanation:

Given :

The bottlenose dolphin travels 40 miles in 2 hours. Or it takes 20 miles in 1 hour.

Now, dividing the distance by unit rate given in the question:

40/20=2 hours

40/5=8 hours

40÷60= 2/3 hour

Therefore,

- the dolphin takes 2 hours for swimming 40 miles.

- the penguin takes 8 hours

- the swordfish takes 2/3 rd of an hour
