Two young mathematicians race to math class.

Check out this dialogue between two calculus students (based on a true story):
Devyn
Riley, I want to go to math class. Now. Let’s race!
Riley
Yes. I love math class. Let’s do race! On, your mark…. Ready. Steady. Go!
Devyn
You may think you’re fast, but I’m catching up!
Riley
Noooooo!
Devyn
Now I’m winning! I’ve never won a foot race in my life!
Riley
Never…give…up!
Devyn
Whew! We both made it to math class at exactly the same time!
Riley
Wow. We should run to every class. Hey I have a question, was there a time during our race that we were running at exactly the same speed?
Which of the following describes the race above?
Devyn was leading until the end, when the race finished in a tie. Riley was leading until the end, when the race finished in a tie. Devyn was leading, then Riley was leading until the end, when the race finished in a tie. Riley was leading, then Devyn was leading until the end, when the race finished in a tie. None of the above.
What can you say about Devyn’s and Riley’s average velocities?
Devyn has the larger average velocity. Riley has the larger average velocity. Their average velocities are equal. None of the above.
Record your guess to Riley’s question: is there a moment during the race where Devyn and Riley were running at exactly the same speed?
Enter your guess of “yes” or “no”, then come back after the Dig-In to see if your guess was correct!
