A) \[5\text{ }km\]
B) \[7\text{ }km\]
C) \[3\text{ }km\]
D) \[4\text{ }km\]
Correct Answer: A
Solution :
Distance (EP) \[=2\,km\Rightarrow BC=2\,km\] \[AB=4\text{ }km\text{ }\Rightarrow \text{ }BD=BC+CD\] \[BD=2+1=3\text{ }km\] Applying Pythagoras theorm - In \[\Delta \,ABD\] \[A{{D}^{2}}=A{{B}^{2}}+B{{D}^{2}}\Rightarrow AD=\sqrt{{{4}^{2}}+{{3}^{2}}}\] So, Ram is \[\]far away from the starting pointYou need to login to perform this action.
