In AB, the ratio of time for a and B to complete the whole journey by bicycle is 4:5. If a and B travel from ab at the same time, 40 minutes later, they meet and continue to move forward. In this way, how many minutes later will b arrive at a than a arrive at B?

5 + 4 = 9, 40 ／ 49-40 ／ 59, = 90-72, = 18 (minutes), a: B arrives at a 18 minutes later than a arrives at B

AB two places, a and B two people ride the whole journey time ratio 4:5, if a and B respectively from AB two places relatively open, 40 minutes meet, meet after
Go ahead, how many minutes later does B arrive at a than a arrives at B

18 minutes
