At noon ship A is 100 km west of ship B. Ship A travels south at 35km/h and ship B travels North at 25 km/hr. At 4pm how fast does the distance between them change?
I don't quite understand how to do this so a complete explanation would be best.

Haha, I have nearly the same problem.
This has to do with implicit differentiation
Use the formula d = v*t
I would say you could also use a^2+b^2=c^2 but they're going in complete opposite directions.
By the way your problem is featured on youtube.
