Answer 1

Answer:

the speed of a boat in water still at 534km hr. if the speed of boat against the stream is 231km hr so it will the speed of the stream is 303km hr

Answer 2

Given: Speed of boat is still water $534km/her$

Speed of boat against the stream is $231 km/hr$

According to the question,

$B=534 km/hr$

upstream speed $=\frac{B-S}{2}$

$231=\frac{534-S}{2}$

$462=534-S$

$S=534-462$

$S=72 km/hr$
