Aman started running from his school, he first ran for 11 km towards south, then he turned towards west and ran √23 km in that direction. How far (in km)and in which direction is Aman now from his school?
If North is called North west , West is called South west , South is called South east and so on . A person walks straight from South west to North east and then turns left . Walks straight and again turns left . Now at what direction he is facing ?
