An eagle starts from its nest and flies 1 km East, the turns North and flies 2 km, then turns West and flies 7 km, then turns to its left and flies 2 km. Where is it now with respect to its nest?
I am facing north. I turn left and walk 30 m. Then I turn right and walk 20 m, then I turn left and walk 10 m and then turning right and walk 50 m. Then I turn left and walk 50 m. In which direction am I from the starting point?
