From a to B, it takes 10 hours for car a and 15 hours for car B. if car a and car B are facing each other at the same time, car a will travel 100% of the total distance when they meet What percentage of the total?

From a to B, it takes 10 hours for car a and 15 hours for car B. if car a and car B are facing each other at the same time, car a will travel 100% of the total distance when they meet What percentage of the total?

It takes 10 hours for car a from a to B, and it takes 15 hours for car B to finish. If car a and car B are facing each other at the same time, what percentage of the total distance does car a travel when they meet?
Distance ratio = speed ratio = inverse ratio of time = 15:10 = 3:2
At the time of meeting, the total distance of car a = 3 / (3 + 2) = 3 / 5 = 60%

It takes 10 hours for car a to go from a to B, and 15 hours for car B to go from B to a?

Meeting time
=1÷（1/10+1/15）
=1÷1/6
=6 (hours)
