From city a to city B, it takes 10 hours for car a and 8 hours for car B. the speed of car a is 25% slower than that of car B () a and 80% slower than that of car B
A. 25% slower
A and B go from city a to city B at the same speed. A goes 12 kilometers before B starts. A returns to city B immediately and meets B at 14 points from city B (14 points from city B to city a)______ Kilometers
A: the distance between the two cities is 24 km. So the answer is: 24
A and B two cars from a city to B city, a car to 50 kilometers per hour to go first, 2 hours later, B car to 75 kilometers per hour to B city
Drive to, the result arrives at B city at the same time, ask AB what is the distance between two places?
After X hours, car B arrives at place B
50(2+x)=75x
100+50x=75x
25x=100
x=4
75*4=300(km)
A: the distance between a and B is 300 kilometers
