Practicing Success
A leaves station P at 8:00 a.m. and reaches station Q at 11:00 a.m. B leaves station Q at 9:00 a.m. and reaches station P at 11:00 a.m. At what time will they cross each other? |
10:00 a.m. 10:05 a.m. 9:48 a.m. 9:52 a.m. |
9:48 a.m. |
Time taken by the first train = 3 hours So ratio of speed = 2 : 3 DIstance = (Speed × time) Relative speed = 3 + 2 = 5 ( when moves towards each other ) = \(\frac{4}{5}\) = 48 minutes So , They meet at 9:00 am + 48 minutes = 9:48 am |
