A. B. two people ride bicycles from two places 65km apart at the same time. Two hours later, the distance is 25km. A rides 2.5km more than B Two people ride bicycles from two places 65km apart at the same time. Two hours later, the distance is 25km. A rides 2.5km more than B per hour. Suppose B travels x km per hour, then a travels -------- km per hour. According to the meaning of the question, the equation is----------------

A. B. two people ride bicycles from two places 65km apart at the same time. Two hours later, the distance is 25km. A rides 2.5km more than B Two people ride bicycles from two places 65km apart at the same time. Two hours later, the distance is 25km. A rides 2.5km more than B per hour. Suppose B travels x km per hour, then a travels -------- km per hour. According to the meaning of the question, the equation is----------------

Suppose B travels x kilometers per hour, then a Travels (x + 2.5) kilometers per hour,
[note that there are two situations in this question]
The first case: 25km after 2 hours, which means 25km before meeting
According to the meaning of the question, the equation is: 2x + 2 (x + 2.5) = 65-25
The second situation: after 2 hours, the distance is 25km, which means after meeting, the distance between Party A and Party B is 25km
According to the meaning of the question, the equation is: 2x + 2 (x + 2.5) = 65 + 25
To sum up: according to the meaning of the question, the equation can be listed as 2x + 2 (x + 2.5) = 65-25, or 2x + 2 (x + 2.5) = 65 + 25

A and B start from two places 65km apart by bike and face each other at the same time. They meet two hours later. If a walks 2.5km more per hour than B, then a's speed is ()

(65 △ 2 + 2.5) △ 2 = 17.5 (km)

Party A and Party B ride bicycles from two places 65km away. After meeting for 2h, it is known that Party A is 2.5km faster than Party B per hour
The speed of a and B is fast
We use a quadratic equation of two variables.

Suppose B travels x kilometers per hour, then a Travels: (x + 2.5) kilometers per hour
2（x+2.5+x）=65
The solution is: x = 15
15 + 2.5 = 17.5 (km / h)
A: B travels 15 kilometers per hour, a 17.5 kilometers per hour

A and B start at the same time from two places 65km apart by bicycle, and meet each other in 2 hours. If a walks 2.5kim more per hour than B, how many kin more per hour

65=2(X+X+2.5) X=15
