The distance between PQ is 203 km. two boats A and B start moving towards each other at the same time from point P and Q respectively. B is upstream and other is downstream. If speed of A and B in still water is 11.4km/hr. and 17.6km/hr. respectively. Then in how much time they will meet.
a) 4hr
b) 5hr
c) 6hr
d) 7hr

Speed of current = x Relative speed = (11.4 + x) + (17.6 – x)
= 29.
Time=203/29=7 hr.
