A and B leave from a and B at the same time and meet each other in two hours. After meeting, the two vehicles continue to move forward. When a arrives at B, B is 60 kilometers away from A. the speed ratio of the two vehicles is known to be 3:2?

If we regard the whole journey as unit "1", then a will travel the whole journey every hour: a will travel the whole journey every hour 33 + 2 △ 2 = 35 △ 2 = 310; after meeting, a will arrive at B with a time of 25 △ 310 = 43 (hours); then the distance between the two places is 60 △ 1-12 × 43 = 60 △ 13, = 180 (kilometers); the sum of a and B's speed is 180 △ 2 = 90 (kilometers / hour); then a's speed is 90 × 35 = 54 (kilometers / hour); and B's speed is 90 × 35 = 54 (kilometers / hour) A: the speed of car a is 54 km / h, and that of car B is 36 km / h



Car a and car B leave from the two places at the same time. Car a travels 54 kilometers per hour and car B 53 kilometers per hour. After five hours, how far is the distance between the two places


The distance between the two places is (54 + 53) X5 = 107x5 = 535km
