[quote=CARLOS,432528]When they pass each other them both are in same place. There is only one but: do we measure from the front or back of train? If front, then the distance from Shanghai is same, if back, the back of train A is closer to Shanghai. To question when do they pass: x100 km/h+x250 km/h = 303 km where x is time in hours next 350x = 303 and then time from start to passing 303/350 = 52min Time for passing is 07:52 Train A travels about 86,5 km in 52 min, train B about 216,5 km. 86,5+216,5 = 303km. The passing place is around Kuatangzhen Carlos[/quote]
