Hi there!
This is what is called a proportion problem.
First, we need to label.
miles
minutes
Next, we add our numbers:
miles 17 x
minutes: 306. 198
Now we are going to cross multiple
17*198 and 306*x
306x=3366
Solve the equation:
x=11
Therefore, the cruise ship can travel 11 nautical miles in 198 minutes.
Hope this is helpful! Let me know if you have any questions:)
