a person at 'A', on land wants to meet another person at 'B'.
A is on land, B is on the sea.
join AB, a point C on it, draw a line BCX, angle bcx=alpha.
line CX is the line of separation of land and sea.straight line AC= 50
meters
CB=30 m
vel of man on land =50 m/s, on sea vel= 10 m/s.

find the minimum time the man needs to reach B?
