Party A and Party B are walking towards each other in two places at the same time. They meet in 8 hours. If they reduce their speed by 3 kilometers per hour and meet in 10 hours, find the distance between the two places

Party A and Party B are walking towards each other in two places at the same time. They meet in 8 hours. If they reduce their speed by 3 kilometers per hour and meet in 10 hours, find the distance between the two places


240 km
Set the relative speed of two people to v
v*8=(v-6)*10
We get v = 30
30 * 8 = 240 (km)



The speed ratio of a and B is 4:3. After they meet, the speed of a increases by 10% and that of B increases by 10%
This way, when a reaches B, B is 26 kilometers away from A. find the distance between a and B?
Sixth grade primary school, the equation is not too complex, seek solutions


Speed ratio: A: B = 4:3
Whole course: 4 + 3 = 7
After meeting, the speed ratio: A: B = 4x (1 + 10%): 3x (1-20%) = 4.4:2.4 = 11:6
When a arrives at B, B leaves a:
4-3 / 11x6 = 26 / 11 (copies)
Each: 26 △ 26 / 11 = 11 (km)
Whole journey: 11x (4 + 3) = 77 (km)
