Answer 1

Answer:

1.After 11 hours, the cruise ship will be  _233.75__nautical miles from the lighthouse.

2.At the start of the journey, the cruise ship was _10.5__ nautical miles from the lighthouse.

3.The cruise ship is traveling at a speed of_21.25_  nautical miles per hour.

Explanation:

Distance covered in 2 hours= 95.5-53NM

=42.5NM

therefore,

$Speed= Distance/time................(1)$

put value of distance and time in equation (1)

therefore,

$speed= 42.5/2hour$

speed=21.25NM/hour

Therefore distance covered in 11 hours= speed* time

$Distance=21.25*11$

=233.75NM

2. Since distance covered in 2 hours is 42.5

therefore, at starting of the journey the cruise distance from light house is

= 53NM-42.5NM

=10.5NM

3. Distance covered in 2 hours= 95.5-53NM

=42.5NM

therefore,

$Speed= Distance/time................(1)$

put value of distance and time in equation (1)

therefore,

$speed= 42.5/2hour$

speed=21.25NM/hour

Therefore Cruise ship is traveling at speed of 21.25NM/hour
