In the forest, two brother rabbits are racing. The younger brother runs 10 steps, then the older brother starts chasing. If the time it takes for the younger brother to run 4 steps equals the time it takes for the older brother to run 3 steps, and the distance the older brother covers in 5 steps equals the distance the younger brother covers in 7 steps, how many steps does it take for the older brother to catch up to the younger brother?
