An object in the current of the Gulf Stream can move 11 miles in 2 hours. At this rate, about how many miles could the object in the Gulf Stream move in 5 hours?

We can use a proportion to solve this problem:

11 miles / 2 hours = x miles / 5 hours

To solve for x, we can cross-multiply and simplify:

2x = 55
x = 27.5

Therefore, the object in the Gulf Stream could move about 27.5 miles in 5 hours.
