A and B start from a and B at the same time, and run in opposite directions. They meet at a distance of 6 km from the midpoint. It is known that the speed ratio of a and B is 7:8 How many kilometers apart?

A and B start from a and B at the same time, and run in opposite directions. They meet at a distance of 6 km from the midpoint. It is known that the speed ratio of a and B is 7:8 How many kilometers apart?

Two cars a and B start from a and B at the same time. They run in opposite directions and meet at 6 km away from the midpoint. It is known that the speed ratio of a and B is 7:8. How many kilometers is the distance between a and B?
The results are as follows
Same time distance ratio = = speed ratio
So the distance between AB and ab is;
6*2/(8/15-7/15)
==12/(1/15)
==180 km
A: the distance between a and B is 180 km

Two cars a and B are facing each other from ab at the same time and meet at 5km away from the midpoint. It is known that the speed of car a is seven times that of car B

A and B two cars from ab at the same time, meet at the distance of 5km from the midpoint. It is known that the speed of car a is five seventh of that of car B, and the distance between AB and ab is calculated
5÷【1/2-5/（7+5）】
=5÷【1/2-5/12】
=5÷1/12
=60 km
