A. The distance between B and B is 600 kilometers. A and B vehicles are facing each other at the same time and meet each other in 5 hours. It is known that the speed of a vehicle is 3 / 5 of that of B vehicle. Then the speed of a vehicle is () km per hour, and that of B vehicle is () km per hour?

A. The distance between B and B is 600 kilometers. A and B vehicles are facing each other at the same time and meet each other in 5 hours. It is known that the speed of a vehicle is 3 / 5 of that of B vehicle. Then the speed of a vehicle is () km per hour, and that of B vehicle is () km per hour?


A = 45 B = 75



The distance between the two places is 600 kilometers. A and B start from the two places at the same time and travel the same way. A's speed is 10 kilometers higher than B's speed per hour. After 4 hours, they meet
The velocity of B is (the equation of one variable plus the result)


Let B's speed be x km / h
(x+10+x)4=600
8x+40=600
8x=560
x=70



If a and B travel in opposite directions at the same time, they will meet in 3 hours. If the speed is reduced by 1.5 kilometers per hour, they will meet in 10 hours to find the distance between the two places


Let the distance be X
So speed and speed are
x/3
1.5% for both
The sum of velocity is x / 3-3
(x/3-3)*10=x
10x/3-x=30
7/3x=30
x=90/7
The distance is 90 / 7



If the speed of each person decreases by 3 km per hour, they will meet after 10 hours to find the distance between the two places


If the distance between the two places is x, then
X/8-6=X/10
Then x = 240km
