Our speed is 30 mph since you didn't say the direction we're heading, if we sped up, or if our direction had changed.
To get our velocity, we'd need our speed, 30mph, and our direction. Using the compass, I can tell that this boat is heading east.
So, the boat is heading east with a speed of 30mph; that is our velocity.
Since we're changing directions now, this is acceleration, right?
Yup!
Since our boat has slowed down, this is also acceleration. Remember: it's when something either changes direction, speeds up, or slows down. It's basically when the speed or direction changes.
So that's why I got a question wrong on that science worksheet yesterday!
A question? You got 3 questions wrong on that 'cause you didn't study with the rest of us!
Oh, be quiet! I had to watch the next episode of Osomatsu-san!
