A boat leaves a dock at 2:00 pm and travels due south at a speed of 20 km/h. Another
boat has been heading due east at 15 km/h and reaches the same dock at 3:00 pm. At
what time were the two boats closest together?
3. The Attempt at a Solution [/b
We actually don't need to use integrals for this(and we haven't really learned how), but I want to.
So a couple of quick questions...
first, integrating 20 equals 20t+c correct?
and second, either the 15km/h or the 20km/h should be negative, and it doesn't matter which one, right?
If those two things are true, I should be all set, if not, I might have more questions. :p
Thanks a lot for the help guys.
