Party A and Party B set out from both places of AB at the same time and walk towards each other. The speed of Party A is 3 / 5 of that of Party B. the meeting point is 20 kilometers away from the midpoint of the two places. How far is the distance between the two places? 2. Team a dug 1 / 3 of the total length of the canal in 8 days, and the rest was completed by team a and team B in the same amount of time?
Party A and Party B set out from both places of AB at the same time and walk towards each other. The speed of Party A is 3 / 5 of that of Party B. the meeting point is 20 kilometers away from the midpoint of the two places. How far is the distance between the two places?
20×2÷（1-3/5）
=40÷2/5
=100 km
2. Team a dug 1 / 3 of the total length of the canal in 8 days, and the rest was completed by team a and team B in the same amount of time?
Cooperation: 8 △ 1 / 3 × [3 / (3 + 2) - 1 / 3] = 24 × [3 / 5-1 / 3] = 24 × 4 / 15 = 6.4 days
It takes 6.4 △ 2 / (2 + 3)] = 6.4 △ 2 / 5 = 16 days for B to dig alone
A and B start from ab at the same time, and run in opposite directions. They meet at the place 20 km away from the midpoint. A's speed is 44 km / h, and B's speed is 48 km / h. find the distance between AB and B
Set the distance between the two places as s km
According to the meaning of the title:
( s/2+20)÷48=( s/2-20)÷44
The solution is s = 920km
That is, the distance between AB and ab is 920km
I hope I can help you
