Chapter 12 Question issue

[elihaun]

The Question at the top of the page asks "In the above example, what does the number 4 represent"? options are: "It's how fast the character rotates" "It's how far the character moves in pixels" "It's how long the rotation takes"

It says the correct answer is "it's how fast the Character rotates" but that is not correct, right? the '2 * delta' is how fast the character rotates, but the 2 itself is the angle it rotates. When multiplied by the delta it makes it a speed, but the 2 itself is just the angle (2 radians is different than 2 radians per second),

Am I tripping, or is that correct?
