Question
Two boats A and B are moving along perpendicular paths in a still lake at night. Boat A move with a speed of 3m/s and boat B move with a speed of 4 m/ in the direction such that they collide sometime, At t = 0, the boats are 300 m part, The ratio of distance traveled by boat A to the distance traveled by boat B at the instant of collision is : -
Options
A.1
B.1 / 2
C.3 / 4
D.4 / 3
Solution
3002 = (3t)2 + (4t)2
300 × 300 = 25t2
t = 60
Ratio =
= 3 : 4Create a free account to view solution
