A will swims 200 miles in five days identify which equation could be used to find out how many miles. It swims in 16 days.

Let's say A swims x miles in 16 days. We can set up a proportion using the given information:

x miles / 16 days = 200 miles / 5 days

To find out how many miles A swims in 16 days, we can cross-multiply and solve for x:

5x = 200 * 16 => 5x = 3200

The equation we can use to find out how many miles A swims in 16 days is:

5x = 3200
