On a circular runway, a starts from point a and B starts from point B at the same time and goes in reverse. After 8 minutes, the two meet. After 6 minutes, a arrives at point B, and after 10 minutes, the two meet again. It takes a week for a circle______ Minutes
The speed ratio of Party A and Party B is: 8:6 = 4:3, 1 △ 1 (6 + 10) × 44 + 3, = 1 △ 116 × 47, = 1 △ 128, = 28 (minutes); a: it takes 28 points for a round trip
One way, a takes 6 minutes to walk the whole way, B takes 10 minutes to walk the whole way, two people from two places to each other, how many minutes to meet?
It takes six minutes for a to walk,
A walks 1 / 6 of the whole course every minute
B: it takes 10 minutes to walk,
B: 1 / 10 of the total walk per minute
The two walked 1 / 6 + 1 / 10 = 8 / 30 = 4 / 15 of the whole course every minute
1 / 6 + 1 / 10 = 1 / 4 / 15 = 3.75 (hours)
RELATED INFORMATIONS
- 1. On the circular runway, a starts from point a and B starts from point B at the same time and goes in the opposite direction. After 8 minutes, the two people meet. After 6 minutes, a arrives at point B, and after 10 minutes, the two people meet again. How many minutes does it take for a circle runway? Let the perimeter of the runway be "1" B 8 points of the journey, a line of 6 points, so the speed ratio of a and B is: 8:6 = 4:3 From the first meeting to the second meeting: 6 + 10 = 16 points, they had a whole journey So the sum of their speed is 1 / 16 That is, the speed of a is: 1 / 16 / (4 + 3) * 4 = 1 / 28 So the time of a week is: 1 / (1 / 28) = 28 points Is this the right way? How?
