1.	At a certain two cars area each 10km from the intersection of roads that are perpendiuclar. Cat A is moving east at 30 km/hr while car B moves north at 50km/hr both toward the intersection. (a) Fnd their closest distance of approach . (B) Where are A and B when they are closest?
Answer» Solution :`(X)/(10)=sin THETA` `x=10sin theta` closest approach `t=(BC)/(sqrt((30)^(2)+(50)^(2))`
