The ratio of the distance carricd away by the water current, downstream, in crossing a river, by a person, making same angle with downstream and upstream are, respectively, as $2: 1 .$ The ratio of the speed of person to the water current cannot be less than a. $1 / 3$ b. $4 / 5$ c. $1 / 5$ d. $4 / 3$
A man rows directly across a river in time $t$ second and rows an equal distance down the stream in $I$ second. The ratio of man's speed in still water to the speed of river water is : (a) $\frac{t^{2}-T^{2}}{t^{2}+T^{2}}$ (b) $\frac{t^{2}+T^{2}}{t^{2}-T^{2}}$ (c) $\frac{T^{2}-t^{2}}{T^{2}+t^{2}}$ (d) $\frac{T^{2}+t^{2}}{T^{2}-t^{2}}$
