@Logrhythm said:i misread the ques....both would be required
but from the 1st d distance can be calculated..isnt it?
@dream_BLAC_2013 said:@[email protected]@ziddiarmaanCan someone plz try this DS sum? A & B start from two ends of a swimming pool 50m long simultaneously. What is the total distance distance covered by them?A. They are meeting 2nd time after startB. A's speed is twice that of B's.I know that this sum looks very simple. I just cant makeout if this book has a printing mistake in the answer keys or is there any hidden factor that I am missing. Plz help
i think both are required..
@DeAdLy said:par we dont know the their speeds so how can we know about distance covered....is second statement is not there
@shattereddream said:@mailtoankit suppose A's Speed as 1 m/sec & B's speed as 50 m/sec tab kya 150 mt travel karte ??
no dude.. you are right..
@shattereddream said:@mailtoankit suppose A's Speed as 1 m/sec & B's speed as 50 m/sec tab kya 150 mt travel karte ??
ekdum correct.. that is why speeds are required..

@techgeek2050 said:y do v need the speed? v know the total distance
what we assume if both are at same speed so total distance should change right 
@mailtoankit said:EDIT : both are required ??total distance covered by them after 2nd meet = 50 + 2*50 = 150dist. covered by A = 2/3*150 = 100dist by B = 1/3*150 = 50
i don't get it. what is the need to calculate the individual distances?
@DeAdLy said:par we dont know the their speeds so how can we know about distance covered....is second statement is not there
1) when two bodies start moving towards each other, then the total distance covered by them for the nth meeting = D + ((n-1)*2D) = (2n - 1)D
2) when two bodies start moving towards the same direction, then for the nth meeting they will cover together (n*2D) distance
PS : ek book mein padha tha..

Well exactly 😁 Thats what I thought it should be but the answer in this book says that the QUESTION CANNOT BE ANSWERED USING BOTH. 😞 In the explanation, it says that u are reqd to find the TOTAL DISTANCE TRAVELLED BY THEM and NOT TOTAL DISTANCE TRAVELLED BY EACH ONE OF THEM. Again nowhere is it mentioned if u have to find the total distance covered during first meet or second meet. So Data Inconsistent.
Was very confused & taken aback at the soln. Thats y i wanted to consult with u guys. Do u think THAT answer is wrong or are we doing it wrong? 😲 Thanks for ur massive help this late :)

haan yaar..we don't need to cal the individual distances
@techgeek2050 said:y do v need the speed? v know the total distance
we need speed i guess 
see bhai..i dont know but speed matters...it depends how fast you can lap from other...so your second meeting point will change

haan you are right bhai..ps.arey main speed ko leke thoda jayada excited ho gaya

haan bhai tu sahi keh raha hai 
arey yar speed ko leke jyada senti ho gaya tha

haan tab nahi karte....my bad..
...chalo answer is neither 1 nor 2..

sorry bhai...but still it doesnt make sense,,,distance will be same...in both the above cases
I dont know if this post is gonna be sent as PG is repeatedly showing errors while posting 😞 Is there anything wrong? 😲 Y is this happening? :O
Coming to the sum, I was getting the answer as only A, B will not be reqd as we have to find the total distance & NOT individual distances. But the answer key messes with my entire logic :(
