3. Two cities A and B are 8 km and 12 km, respectively, north of a river which runs due east. City B being 15 km east of A. a pumpingstation is to be constructed (along the river) to supply water for the two cities. Where should the station be located so that the amount ofpipe is a minimum?4. An open top rectangular tank with square bases is.to have a volume of 10 cubic meters. The material for its bottom cost P 150.00 persquare meter, and that for the sides is P 60.00 per square meter. Determine the most economical dimensions of the tank.5. Two posts, one 8 ft. high and the other 12 ft. high, stand 15 ft. apart from each other. They are to be stayed by wires attached to asingle stake at ground level, the wires running to the tops of the posts. How far from the shorter post should the stake be placed to usethe least amount of wire?
