A clock's minute hand has length 4 and its hour hand length 3.

What is the distance between the tips at the moment when it is increasing most rapidly?

Ok, after correcting it back to 5.75t, the answer becomes 7. Then t=(180+360n)/5.5=(360+720n)/11, where n=0,1,2,... There is no limit on n (assuming the clock keeps working) since time goes on forever.
