A) 6 km
B) 8 km
C) 10 km
D) 14 km
Correct Answer: B
Solution :
[b] Let the distance = d km Time taken to row upstream \['{{t}_{1}}'=\frac{d}{5-3}=\frac{d}{2}\] ? (1) Time taken to row downstream \['{{t}_{2}}'=\frac{d}{5+3}=\frac{d}{8}\] ? (2) \[{{t}_{1}}+{{t}_{2}}=5\] (Given) \[\therefore \,\,\frac{d}{2}+\frac{d}{8}=5\] \[\Rightarrow \,\,\,\frac{4d+d}{8}=5\Rightarrow d=8\,km\] \[\therefore \] Distance of the place = 8 km.You need to login to perform this action.
