MAHALAKSHMI A X-Y=14=>X=14+Y;X+Y=40=>14+2Y=40 2Y=26 Y=13Km/hr and speed of the boat is 27km/hr
MANISH A (UPSTREAM SPEED - DOWNSTREAM SPEED) / 2
Nidhi B X
Sai Varsha c relative speed=14*40/(40-14)=34
y d because ans is 27
MANASA A x-y = 14 x+y = 40 x = speed of boat y = speed of stream
SABINA D the boat is travelling in opposite direction while going downstream to that of moving in upstream so relative speed is 14+40=54km/hr
Onkar A speed of stream-speed of boat=14, speed of stram+speed of boat= 40
bhuvaneshawari A Speed of boat upstream=speed of boat-speed of stream=(u-v)=14km/hr..................eq-1 Speed of boat downstream=speed of boat+speed of stream=(u+v)=40km/hr..............eq-2 eq-2 - eq-1 speed of stream=v=13km/hr
Vignesh b 111
JEENA a speed of stream=1/2*(downstream-upstream) =1/2*(40-14) =13km/hr
Priya A speed of stream = 1/2 * (downstream - upstream)
SNEHLATA D because boat moving towords the stream
sudev c iits c believe me
manjeet a x+y=40 , x-y=14, add both then get 2x=54 => x=27 and y=13
Divya A Downstream(U) = 40km/hr upstream(V) = 14 km/hr Speed of stream = 1/2(U-V) = 1/2(40-14) = 1/2(26) = 13 km/hr Since stream is pushing back hence difference is been used..
baba b 40-14
Akshay a v-c=14(upstream) v+c=40(downstream) => v=27 => c=13km/hr
Correct Answer: 13 km/hr
Solution:
Speed of stream = ½( down stream – up stream )
= ½ ( 40 – 14 ) = 13 km/hr.
