Given that the lengths of the paths of a ball thrown with different speeds by two boys are the same, and the average speed for the first and second throws are respectively 90 km/h and 162 km/h, then what is the time taken by the first throw to cover the length if the same for the second thrown is one second? दिया गया है कि दो लड़कों के द्वारा अलग-अलग चाल से फेंकी गयी गेंदों के मार्ग की लंबाई समान है तथा पहले और दूसरे फेंकी गयी गेंदों की औसत गति क्रमशः 90 किमी / घंटा और 162 किमी / घंटा है, अगर दूसरे फेंकी गयी गेंद ने इस लंबाई को कवर करने के लिए एक सेकंड का समय लिया तो पहली फेंकी गयी गेंद द्वारा इस लंबाई को कवर करने के लिए लिया गया समय क्या है?

Given that the lengths of the paths of a ball thrown with different speeds by two boys are the same, if they take 0.6 seconds and 1 second respectively to cover the said length, what is the average speed of travel for the first throw, if the same for the second is 96 km/h? दिया गया है कि दो लड़कों के द्वारा अलग-अलग चाल से फेंकी गयी गेंदों के मार्ग की लंबाई समान है | यदि उन्हें इस लंबाई तक जाने में क्रमशः 0.6 सेकंड और 1 सेकंड लगते हैं, तो पहली थ्रो में गेंद की औसत चाल ज्ञात करें, यदि इसी के लिए दूसरी गेंद की ओऔसत चाल 96 किमी/घंटा है|
