A) 15.4 km/hr
B) 14.5 km/hr
C) 14.4 km/hr
D) 14 km/hr
Correct Answer: C
Solution :
Suppose speed of Bimal = x km/hr Then, \[\frac{100\times 18}{5x}-\frac{100\times 18}{18\times 5}=5\] \[\frac{100\times 18}{5x}=25\] \[x=\frac{100\times 18}{25\times 5}\] \[=14.4\,\,km/hr\]You need to login to perform this action.
