Two boats start towards each other, from the two points exactly opposite of each other on the opposite banks of a river, simultaneously. They meet at a distance of 410 m from one of the banks and continue sailing further till they reach the opposite banks. They take rest for 1 hr each and start off the return journey taking the same route. Now they meet at a distance of 230 m from the other bank. Find the distance between the two banks. (Assume that river water is still.)
a) 750 m
b) 840 m
c) 1100 m
d) 1000 m
How we will take that 1 hour rest into account while solving ?

A and B start moving towards each other simultaneously on a straight line from cities P and Q respectively. After travelling some distance, B takes a 30° turn to his left with respect to his original direction. 2 hour after B turns, A takes a 90° turn to his right. A travels 60 km after turning, before meeting B. They meet 10 hour after starting their journey. A and B together travel 170 km with time ratio 8:9 respectively before turning and arrive at the meeting point simultaneously. If A and B had not turned, after how many hours would they have met?
