Xiaojun's walking distance is 14 more than Xiaohong's, but Xiaohong's walking time is 110 more than Xiaojun's______ ．

Xiaojun's walking distance is 14 more than Xiaohong's, but Xiaohong's walking time is 110 more than Xiaojun's______ ．

The distance ratio of Xiaojun and Xiaohong is: (1 + 14): 1 = 54:1 = 5:4; the time ratio of Xiaojun and Xiaohong is: 1: (1 + 110) = 1:1110 = 10:11; then the speed ratio of Xiaojun and Xiaohong is: (5 ﹣ 10): (4 ﹣ 11) = 510:411 = 11:8

Xiaojun's distance is 1 / 4 more than Xiaohong's, but Xiaohong's time is 1 / 9 more than Xiaojun's?

Xiaohong's walking distance is 1, Xiaojun's walking distance is (1 + 1 / 4)
The time spent by Xiaohong is (1 + 1 / 9), and the time spent by Xiaojun is 1
Then: Xiaohong walking speed: 1 / (1 + 1 / 9) = 9 / 10
Walking speed of small army: (1 + 1 / 4) / 1 = 5 / 4
Speed ratio of Xiaohong and Xiaojun: 9 / 10:5 / 4 = 18:25
