A cruise ship can cover 21 nautical miles in 483 minutes. How many nautical miles will it travel in 230 minutes?

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.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
