A and B started their journeys from X to Y and Y to X, respectively. After crossing each other, A and B completed the remaining parts of their journey in `6 1/8` h and 8h respectively. If the speed of B is 28 km/h, then the speed (in km/h), then the speed (in km/h) of A is :
A और B ने क्रमशः X से Y और Y से X तक की अपनी यात्राएं शुरू की | एक-दूसरे को पार करने के बाद, A और B ने अपनी यात्रा का शेष भाग क्रमशः `6 1/8` घंटे एवं 8 घंटे में पूरा किया | यदि B की चाल 28 किमी/घंटा है, तो A की चाल ( किमी/घंटा में ) ज्ञात करें |
