Ankit walks 17 km towards east. He turn left and walks 17 km. He turns left again and walks 24 km to reach point A. What is the straight line distance (in km) between the starting point and point A?
Let Ankit starts from point S walks 17 km towards east to reach T. He turn left and walks 17 km northwards to reach B. He turns left again and walks towards west 24 km to reach point A.
=> $$(AS)^2=(AR)^2+(RS)^2$$
=> $$(AS)^2=(17)^2+(7)^2$$
=> $$(AS)^2=289+49=338$$
=> $$AS=\sqrt{338}=13\sqrt2$$ km
$$\therefore$$Â Distance between the starting point and point A = $$13\sqrt2$$ km
=> Ans - (A)
