Two straight roads intersect at right angles in Kingstonville. Car A is on one road moving toward the intersection at a speed of 50 mph. Car B is on the other road moving away from the intersection at a speed of 30 mph. We wish to know how fast the distance between the cars is changing when car A is 3 miles from the intersection and car B is 4 miles from the intersection.

Write an equation involving the variables whose rates of change either are given or are to be determined. Then, using the chain rule, implicitly differentiate both sides of the equation with respect to time t.

Please help me name that part! I would prefer to know the complex medical name for this part or chemical or whatever it may be that controlls "fun" in the brain.

FYI: This is not homework... as I graduated college years ago.

10 points to the best answer!
