A and B travel the same way from a and B. It takes 9 hours for a car to complete the whole journey, and 6 hours for B car to complete the journey. The distance between a and B is 50 kilometers when they meet Equation, formula,

A and B travel the same way from a and B. It takes 9 hours for a car to complete the whole journey, and 6 hours for B car to complete the journey. The distance between a and B is 50 kilometers when they meet Equation, formula,

Let the distance between a and B be unit length "1", then,
The speed of car a is 1 / 9,
The speed of car B is 1 / 6;
A. B the distance between the two places is:
50*2/(1/6-1/9)*(1/6+1/9)
=100/(3/54)*15/54
=100*54/3*15/54
=100*15/3
=500km .

It takes 10 hours for car a to complete the whole journey and 8 hours for car B to complete the whole journey. The distance between the two places is 30 kilometers when they meet?

When did you meet
1 ÷ (1 / 10 + 1 / 8) = 40 / 9 hours
When they met, car a went all the way
1/10×40/9＝4/9
What is the distance between the two places
30 (1 / 2-4 / 9) = 540km

A and B leave the two cities at the same time. After three hours of meeting, car a travels 44 kilometers per hour, while car B takes seven hours to complete the journey,
After meeting, how many kilometers can car a travel to reach city B?

A drove three hours and B drove four hours
A is 4 / 3 times faster than B
B's speed is 44 * 3 / 4 = 33 km / h
B: it's 99 kilometers in three hours
99 / 44 = 9 / 4 hours

A and B leave AB city at the same time. After 5 minutes, they meet in 5 out of 11 hours. It is known that a takes 12 hours to complete the whole journey,
How many hours does it take B to complete the whole journey?

1 ÷ [1 / (5 and 5 / 11) - 1 / 12]
=1÷【11/60-1/12】
=1÷1/10
=10 hours
