Everyday, Deepak rides a bicycle on a road from point A to point B at a constant speed. Buses ply to and fro between points A and B. Everyday, Deepak, the bus going from A to B and the bus going from B to A meet at a roadside restaurant. Today, Deepak started 30 minutes later than his usual time. As a result, he met the bus going from B to A at a distance 5x short of the restaurant 5 minutes after the usual time. Similarly, he meets the bus going from A to B at a distance 8x short of the restaurant 10 minutes before the usual time. What is the ratio of the speeds of Deepak, the bus going from A to B and the bus going from B to A?
