Xiao Ming and Xiao Liang walk from school to the library. Xiaoming needs 10 minutes, and Xiao Liang needs 12 minutes. Why did Xiaoming and Liang Xiao use a speed ratio of 6:5?
Solution: Let the distance between the school and the library be S,
According to the speed distance formula, Xiaoming's speed v=s/t=s/ 10.
The speed of small light v=s/t=s/ 12.
So the speed ratio used by Xiao Ming and Liang Xiao is (S/ 10): (S/ 12) = 6: 5.
