Father and son went to Yueping Park along the same route from home. They run at the same time, when father runs a fifth of the distance.
The speed of two people is the same! So their speed ratio is 1/5 to 15/ 100, which is equal to 3/4. After that, the son ran 600 meters, the same as the rest of his father's running. Then the ratio of the distance his son ran to the distance his father ran during this period is 3/4 ... It can be concluded that his father ran 600/x = 3/ during this period.
