A boat sails downstream from point A to point B, which is 10 km away from 4, and then returns to A . If the actual speed of the boat (in still water) is 3 km/h, the trip from A to B takes 8 hours less than that from B to A . What must the actual speed of the boat for the trip from  A to B to take exactly 100 minutes?
