A and B two cars simultaneously from AB two opposite, 6 hours meet, after meeting a car continue to drive 4 hours to arrive at B, B line to complete the whole how many hours?

A and B two cars simultaneously from AB two opposite, 6 hours meet, after meeting a car continue to drive 4 hours to arrive at B, B line to complete the whole how many hours?


It takes 4 hours for car a to travel 6 hours. The speed of car a is 6 / 4 of that of car B = 1.5 times
Then it takes 6 hours for car a and 9 hours for car B. that is to say, it takes 9 hours for car B to arrive at a after meeting
From the starting point, the second car takes 6 + 9 = 15 hours



Two cars of a and B run in opposite directions from ab at the same time. After meeting, a goes to B in 4 hours and B goes to a in 9 hours. How many hours does it take for a and B to complete the whole journey?


Let t be the meeting time and o be the meeting place
It can be seen from the equal time ratio and distance ratio of Party A and Party B in the two sections of the road
t:4=AO:OB,t:9=BO:OA
So t: 4 = 9: t
So t = 6
Then the answer can be found
In fact, when you see the numbers 4 and 9, you should know that 6 in the ratio is likely to work
Sometimes, just looking at numbers can solve problems, as long as you are sensitive enough to numbers



Party A and Party B are traveling from AB to B at the same time. They meet in 10 hours. After meeting, Party A will travel 6 hours to B. how many hours will it take for Party B to finish the whole journey


B left when we met
6/(10+6)=3/8
The whole process of B needs 10 △ 3 / 8 = 80 / 3 hours



Two cars a and B go from a and B at the same time. They meet in six hours. After meeting, they continue to move forward. In four hours, car a arrives at B. how many hours does it take car B to complete the whole journey?


The speed of car a is: 14 + 6 = 110, the sum of speed of car a and car B is: 1 △ 6 = 16, then the speed of car B is: 16-110 = 115, and the time for car B to complete the whole journey is: 1 △ 115 = 15 (hours). A: it takes 15 hours for car B to complete the whole journey
