SUMMARY
The discussion centers on calculating the ratio of speeds between two skaters after they push off from each other. Skater 1 has a mass of 55 kg and Skater 2 has a mass of 75 kg. Using the principle of conservation of momentum, the ratio of their speeds can be determined as 75:55, simplifying to 15:11. This conclusion is reached by applying the conservation of momentum equation, which states that the total momentum before the push must equal the total momentum after the push.
