Four persons K, L, M, N are initially at the four corners of a square of side d. Each person now moves with a uniform speed v in such a way that K always moves directly towards L, L directly towards M, M directly towards N and N directly towards K. The four persons will meet at a time ...... 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
