Hurry! Ten minutes to! Very simple elementary school mathematics sixth grade score application problem! Xiaoyue walked from the East Village to the West Village. After walking 3 / 8 of the whole venue, she walked 60 meters, 20 meters more than the key point. How many meters is the distance between the East and west villages?

A piece of cloth can be made into 18 identical coats and 9 pairs of trousers, or 14 identical coats and 15 identical trousers. Then, how many coats can be made out of the whole cloth?
18 identical tops and 9 pairs of pants = 14 identical tops and 15 identical pants
There are four less coats and six more trousers
4 tops = 6 pants
9 quilts = 6 tops
18 + 6 = 24 pieces
A full coat can make 24 pieces
School to buy 8 basketball and 10 volleyball, a total of 960 yuan. Known to buy 7 volleyball money can buy 4 basketball, each volleyball how much?
7 volleyball is equivalent to 4 basketball, then 8 basketball is equivalent to 14 volleyball
So 960 yuan can buy 24 volleyball
Formula: price of each Volleyball: 960 ^ (10 + 8 ^ 4 × 7) = 960 ^ 24 = 40 (yuan)
