There is a 400 meter track on the track and field, the width of the track is 1 5 meters, and the sta

400 meters on the track, exactly half a lap. At the point of symmetry of the finish line about the center of the field:

The first lane of the 200-meter starting line is half of 400 meters, and the second starting line (based on the 400-meter finish line) is ahead of the first starting line wn=[(n-1)*Based on the first starting line).

where n is the number of channels and pi.

1-8) values (unit: meters) are 0,,,1-8 items) in advance (unit: meters): 0,,, if it is calculated as a math problem wn=[(n-1)*, it can be omitted, and the values are as follows:

1-8) values (unit: meters) are 0 ,,,1-8) in advance (unit: meters): 0,

The question is not specific enough, not good!

A 400-meter race is held on the 400-meter circular running track of the old first track, which is 1 meter wide and adjoins the starting line of the two Hanshi runways.

Difference: The second lane is ahead of the first starting line: [(2-1)*m.

The 3rd lane is ahead of the 2nd starting line: (3-2)*1*2 = meters.

The 4th lane is ahead of the 3rd starting line: (4-3) * 1 * 2 = meters.

Summary. Hello!

The second lane is ahead of the 400-meter starting line of the first lane (Wu = m), and each subsequent lane is ahead of the 400-meter starting line of the previous road (Wu = m). At 200 meters, the advance number is half of the advance number corresponding to 400 meters, i.e. meters, meters. <>

Hello! The second lane is ahead of the 400-meter starting line of the first lane (Wu = m), and each subsequent lane is ahead of the 400-meter starting line of the previous road (Wu = m). At 200 meters, the advance number is half of the advance number corresponding to 400 meters, i.e. meters, meters. <>

[Compare hearts].

Pro, each lane should be advanced by meters, the second lane is earlier than the first 400-meter starting line (Wu = m), and each subsequent road is ahead of the previous 400-meter starting line Wu = m).

Difference: meters (because the two corners are a circle, the straights are the same, and the curve difference is the difference between the circumferences of the two circles) with a 400-meter standard runway radius of 36 meters, and the width of the runway is meters The circumference of the first lap of the runway is 2*, and the circumference of the second lap runway Pikey is 2*

The 400-meter race is carried out on the 400-meter circular track, the runway is 1 meter wide, and the starting line of the two tracks is different from the two tracks

The second lane is ahead of the first starting line: [(2-1)*m.

The 3rd lane is ahead of the 2nd starting line: (3-2) * 1 * 2 = meters.

The 4th lane is ahead of the 3rd starting line: (4-3) * 1 * 2 = meters.

Answering process:

The 400-meter standard runway has a radius of 36 meters and a runway width of one meter.

The circumference of the first lap of the track is 2*m.

The circumference of the track on the second lap is 2*m.

The circumference of the track on the second lap minus the circumference of the track on the first lap.

Meters = meters. Because I only ran half a lap of 200 meters.

So m2=m.

Answering process:

The 400-meter standard runway has a radius of 36 meters and a runway width of one meter.

The circumference of the first lap of the track is 2*m.

The circumference of the track on the second lap is 2*m.

The circumference of the track on the second lap minus the circumference of the track on the first lap.

Meters = meters. Because I only ran half a lap of 200 meters.

So m2=m.

The width of the runway means that the radius of the two circular runways is different by meters, and the circumference is 2*meters apart, that is, the starting line is advanced by meters.

should be in advance meters.

Problem solving process:

Isn't it easier to understand by drawing a picture for you?

The 400-meter standard runway has a radius of 36 meters and a runway width.

The circumference of the first lap of the track is 2*m.

The circumference of the runway on the second lap of the runway is 2*.

meters wide of the runway, the circumference of the second lap of the state wheel runway.

The circumference of the track on the second lap minus the circumference of the track on the first lap.

Meters = meters. Meters = meters.

The width of the runway slag is meters, and the adjacent runway peripheral runway needs to be advanced by meters.

The width of the runway is meters, and the runway around the adjacent runway needs to be advanced by meters.
