Mam last questions could be as?.! Let the speed of boat be x km/h Let the speed of stream be y km/h Now. Case 1:- Upstream distance =16km Downstream distance =24km Time taken by boat is 6hrs So, t(upstream)+t(downstream)=6hrs D/s + D/s It will be :- 16/(x-y)+24/(x+y)=6hrs 2[ 8/ (x-y) + 12/(x+y) ]=6 => 8x + 8y +12x -12y /(x-y)(x+y) = 3 The equation will be:- 20x-4y=3(x²-y²)...................... eqñ. 1 Similarly with another case:- The equation will make:- 8x -4y=x²-y²................................eqñ. 2 By substituting the value of x²-y² in eqñ 1 The procedure will as:- 20x-4y=3(8x-4y) 20x -4y=24x-12y -4x=-8y 4x=8y x=2y..................,..eqñ. 3 Putting the value of eqñ 3 in eqñ. 1 20(2y)-4y=3[ (2y)²-y²] 40y -4y=3(4y²-y²) 36y=3(3y²) 36y=9y² 36=9y 36/9=y Y=4 Then the speed of boat or value of x will be 8 (by eqñ. 3) Speed of boat =8km/h. Speed of stream=4km/h. ~$atyam

Can u tell why in Q2 we added the time of upstream and downstream why didn't we subtract
@vivaansinha1741

@@manshishortvideos8998 because 1 hour 40 minutes is the total time. The sailor is going downstream and returning upstream in 1 hour 40 minutes. It is the total time taken by him to travel downstream and then upstream. so it will be : (time taken in upstream) + (time taken in downstream)

@@villagerss.tgamer5937 dude that's soo easy for you cuz you're a North indian and of course it's ur first language . but you should know that only 40 % of India knows Hindi. I hope this makes sense to you. You actually can't offense someone just because he/ she can't speak his mother tongue..and secondly he said that he's from pondicherry so of course hindi isn't his first language and that's the reason why we have 22 scheduled languages in our Constitution and of course it doesn't promotes any language in particular. .. That's why we don't have a national language.. So I just hope you got it and you won't do the same thing to someone in future too.. My intentions were not to hurt you or something after all we all our brother☺ and sisters so let's spread love only.
