About 50 cents a step. First, find out the steps from home to school, and then calculate the distance from home to school. One step is about 50 cents, and it takes about 600 steps from home to school. 5× 600 =3000 (decimeter) =300 (meter).
It's about 300 meters from home to school. The key to solve this problem is to estimate the length flexibly with body measurements and make it clear that one step is about 5 decimeters.
In mathematics, distance is one of the most basic concepts in functional analysis. The distance space defined by it connects topological space with normed linear space and other spaces, and it is the first contact concept of learning functional analysis. Distance refers to the length of a straight line between any two points.
The importance of learn mathematics:
1. Mathematics is closely related to our life. To say that the real effect of learning mathematics is not reflected in exam-oriented education, but in my own thinking about the future.
2. The importance of mathematics is self-evident. Mathematics is the foundation of all sciences and an important channel to cultivate logical thinking. It can be said that every major progress of our mankind is strongly supported by mathematics.
3. The application of mathematical knowledge in life is everywhere. From the calculation of daily living costs, to astronomy, geography, quality control, agricultural economy, aerospace, there are shadows of using mathematics.
