A and B leave from the East and West. After 8 o'clock, the two vehicles meet at 32km from the midpoint. A runs 48km per hour, B runs 48km per hour? Lie equation: 4.5 times of the decimal is 22.5 times more than 3 times of the decimal? What's the quotient of 25 plus two fifths and dividing by seven ninths?

1. If Party A and Party B meet at 32km from the midpoint, the absolute value of the distance difference between Party A and Party B is 64km
|48—V|*8=64
V = 40 km / h or V = 56 km / h;
2. If the decimal is x, there will be
If 4.5X = 3x + 22.5, x = 15.0;
3.（25+25*0.4）*9/7=45；
