A and B leave from ab station at the same time. After 6 hours of meeting, it is known that it takes 10 hours for car a to complete the whole journey, and how many hours for car B to complete the whole journey?
If the velocity of a is x and the velocity of B is y, 4x = 6y, 10x equals 15y
A and B start from a and B at the same time and travel in opposite directions. A travels 80 kilometers per hour, and B travels 10% of the whole journey per hour. When B reaches 58, a reaches B at 16 of the whole journey. How many kilometers are there between a and B?
The speed ratio of a and B is: (1-16): 58 = 56:58 = 4:3; therefore, the speed of B car per hour is: 80 △ 4 × 3 = 20 × 3 = 60 (km); the distance between AB and a: 60 △ 10% = 60 △ 0.1 = 600 (km); a: the distance between a and B is 600 km
A and B start from a and B at the same time and travel in opposite directions. A travels 80 kilometers per hour and B travels 10% of the whole journey per hour. When B reaches the end of the whole journey, a and B travel 80 kilometers per hour,
You can get to B by the whole journey. How far is ab?
A and B start from a and B at the same time and travel in opposite directions. A travels 80 kilometers per hour, B travels 10% of the whole journey per hour. When B reaches five eighths of the whole journey, a can reach B by one sixth of the whole journey
The speed ratio of car a and car B is 2:3. It is known that it takes 9 hours for car a to complete the whole journey, and it takes 9 hours for two cars to meet
Few hours?
1 / (1 / 9 + 1 / 6) = 3 and 5 / 1 hour
