Sonal and Deepali started swimming towards each other simultaneously from points A and B respectively situated at two ends of a 96 km long stretch of a river. Destinations of Deepali and Sonal were points A and B respectively. Both of them could swim at 12 kmph in still water. When they started, it was high tide and Sonal swam against the stream. As soon as they met, the tide changed to ‘low tide’ and then Deepali faced the resistance of the stream. Deepali and Sonal took 7 hr 12 min and 8 hr 34 2/7 min to reach their destinations respectively. [Speed of the stream during high and low tide need not necessarily be the same.] "
P and Q are two stations. Train A started from P towards Q at 6.00 a.m at 90 kmph. At the same time train B started from R an intermediate station 60 km from P and travelled towards Q at 60 kmph. Train C started from Q towards P at 7.00 a.m at 120 kmph. All the train crossed each other simultaneously. find PQ IN (KM)
