After 100 seconds, Xiao Ming ran: 3*100=300 meters, and Xiaoqing ran: 5*100=500 meters.

Two encounters, i.e. two people ran two laps, so the total length of the track is: (300 + 500) 2 = 400 meters.

Set this circular track to be x meters long, because Xiao Ming and Xiao Qing ran in the opposite direction, so when they met for the second time, they circled the track a total of 2 times, that is, 2x meters, and took 100 seconds.

2x=（5+3）x100

x=800/2

x=400A: The runway is 400 meters long.

Xiao Ming (3 * 100) = 300 meters Xiao Qing (5 * 100) = 500 meters.

300+500）|2 = 400 meters.

The runway is 400 meters long.

Xiao Ming ran 3 meters per second, Xiao Qing ran 5 meters per second, after 100 seconds, so Xiao Ming ran 300 meters, Xiao Qing ran 500 meters, they ran a total of 800 meters, because they met for the second time on the track, so divide by 2, get 400 meters.

The circumference of this parallelogram is 15+15=30 (meters).

Xiaohua and Xiaoli learn words, Xiaohua learns 2 more words a day than Xiaoli, Xiaoli stopped halfway for 15 days and didn't learn, 40 days later, Xiaohua learned exactly 2 times as many words as Xiaoli, and how many words did the two learn at this time.

Solution: If Xiaohua learns x words, then Xiaoli learns x words.

x÷40－2=½x÷(40-15)

Solution: x=400, so Xiaohua learned 400 and Xiaoli learned 200.

6/6 + 6/6 +（6-6）=2

Since I didn't know how to divide the sign in it, I used it instead.

It took 50 minutes between 9:50 and 9 a.m.

The dragon rides for 50-10 = 40 minutes and walks a distance of 250 40 = 10,000 meters.

Xiaohai walked for 50 minutes, walked 60 50 = 3000 meters, because he came back to meet and walked 2 whole journeys, the whole journey = (10000 + 3000) 2 = 6500 meters.

A: The school is 6500 meters away from the bookstore.

Reading 16 pages a day means reading 4 more pages a day than before. Because I read 4 more pages a day, I not only offset the remaining 40 pages, but also advanced the number of pages by 3 days (3*12=36 pages). So the second time, it only took him 19 days (40 + 12 * 3 = 76, 76 4 = 19) to read all the pages.

Then the whole book has 16 * 19 = 304 pages.

Solution: Suppose the estimated number of days for Xiao Ming to read a storybook is x days, and get 12x+40=16(x-3).

12x+40=16x-48

12x-16x=-48-40

4x=-88

x=22, so the book has 12x+40=12*22+40=304 (pages) or 16(x-3)=16*(22-3)=16*19=304 (pages).

A: The book is 304 pages long.

Set the original planned number of days to x days.

12x+40=16(x-3)

x = 2222 * 12 + 40 = 304 pages.

Read it 3 days in advance, if you continue to read it in these 3 days, you can read 16 3 = 48 pages, in the estimated number of days than 12 pages per day, a total of 48 + 40 = 88 pages, read 16-12 = 4 pages more per day, the original plan is 88 4 = 22 days, 22 12 = 264 pages, 264 + 40 = 304 pages.

Assuming the estimated number of days is x days, the book has a total of y pages.

12x+40=y

16(x-3)=y

x=33y=304

The book has 304 pages.

304 pages. There are a total of x pages.

Formula: (x-40) 12=(x 16)+3

Set a plan to look at x days.

12x+40=16x—3*16x=22

That's how it should be.

The book is 304 pages long and is expected to be read in 22 days.
