Hi, can you please clarify the question further? There appears to be a conufsion from my end regarding how a ball can hit the shot. Assuming you mean the ball is hit for a shot in 25 seconds, and each shot implies 50 points ( please clarify how may points would be get if we hit the shot). The, in 4 hours, we would have 4*60*60 seconds. To find out the number of shots, simply divide this number by 25, and then to get the score, multiply it by 50.

This is just a working mechanism. Once you clarify the question, I would be able to assist you further!
