A) \[2.2\text{ }km\]
B) \[2.7\text{ }km\]
C) \[\text{11}\sqrt{3}\text{ }km\]
D) \[2.40\text{ }km\]
Correct Answer: D
Solution :
According to question, Distance covered from House to Bank \[=\sqrt{{{(5-2)}^{2}}+{{(8-4)}^{2}}}=\sqrt{9+16}=5\,km\] Distance covered from school to office \[=\sqrt{0+{{(26-14)}^{2}}}=12\,km\] \[\therefore \] Total distance covered by Ayush \[=5+10+12=217\,km\] Also, Distance covered directly from House to office \[=\sqrt{{{(13-2)}^{2}}+{{(26-4)}^{2}}}=11\sqrt{5}km\] \[\therefore \] Required distance \[=27-11\sqrt{5}=2.40\,km\]You need to login to perform this action.
