Answer: About 10.95 nautical miles

Step-by-step explanation: First, lets find how many minutes the cruise ship can cover in 1 nautical mile.

In order to do that divide 21 nautical miles by 21 and 483 minutes by 21.

21/21 = 1 nautical mile                                            483/21 = 21 minutes

Now, divide 230 minutes by 21 minutes, which equals about 10.95.

So, in 230 minutes the cruise ship will travel about 10.95 nautical miles.

Aliun [14]

Answer:

He would need 58 yards of material.

Step-by-step explanation:

If there are 4 sets of pillows and comfoters, that means there are 8 pillows and 4 comfoters.

If each pillow uses 0.75 yards of material, 8x0.75= 6

If each comfoters uses 13 yards of material, 4x13= 52

6+52= 58 yards of material.
