Correct Answer: $6\frac{1}{2}$ km/hr

Solution : Given: Downstream Speed = 1 km in $7\frac{1}{2}$ minutes
= $\frac{1}{\frac{15}{2×60}}$ = 8 km/hr
Upstream Speed = 5 km/hr
Speed of boat in still water = $\frac{\text{(Downstream Speed + Upstream Speed)}}{2}$
= $\frac{8+5}{2}$ = $6\frac{1}{2}$ km/hr
Hence, the correct answer is $6\frac{1}{2}$ km/hr.
