Q. The speed of a stream is 3 km/hr and the speed of a man in still water is 5 km/hr. The time taken by the man to swim 26 km downstream is :
Answer: $latex 3\frac{1}{4}hrs&s=1$
Notes: $latex \mathbf{3\frac{1}{4}hrs}&s=1$
$latex Time = \frac{Distance}{Rate Downstream}&s=1$ $latex = \frac{26}{5+3} = \frac{13}{4} = 3\frac{1}{4} hours&s=1$ Hence option [C] is correct answer.
