Question

#2 Jamal is an apprentice on a boat on Long Island Sound. He is helping the captain collect samples of

marine life for an environmental study, and the captain is teaching him about nautical navigation.
When the boat leaves the environmental station, it will return to its home port 9 nautical miles away.
If
the boat maintains a constant speed of 15 knots (nautical miles per hour), how many minutes will the
trip take?​

Answer 1

The trip will take 36 minutes.

Explanation:

This question can be solved using a rule of three.

The boat maintains a constant speed of 15 knots (nautical miles per hour). How many minutes it will take to return to its home port 9 nautical miles away?

So in 60 minutes, 15 nautical miles. How many minutes for 9 nautical miles?

60 minutes - 15 nautical miles

x minutes - 9 nautical miles

`15x = 60*9`

`x = (60*9)/(15)`

`x = 36`

The trip will take 36 minutes.
