I have no clue how to even begin to work this problem or what the little triangle in front of the d means. If someone could explain, that'd be great. Thanks!

 

An ant started at a distance of 20 cm from a camera and began crawling directly away from it. 5 seconds later, the ant was 28 cm from the camera. If d is the distance of the ant from the camera, what is \(\Delta d?\)

 

Is the answer 8? Do I just subtract the two?

You do just subtract the two.  The uppercase Greek letter \(\Delta\)  is often used to indicate the change in something; so \(\Delta d\)  means the change in d.
