Wrong (Question: 252339.0 )

Toh 8 kyun bta rhe Ho answer agar 6 nikala h

Question:
Two boats A and B start towards each other from two places, 480 Km apart. If A proceeds down and B up the stream. The sum of speed in still water of A and B is 80 Km/h. Find in how much time they will meet?
Options:
A) 3 hours 
B) 5 hours 
C) 6 hours 
D) 8 hours 
Solution:

Ans: (c)

Speed of boat ‘A’ = A

Speed of boat ‘B’ in still water = B

Speed of stream = x

A + B = 80

(A + x)t + (B – x)t = 480

(A + B)t = 480

t = 480 = 480/80  = 6

t = 6 hours
