text: The solution is in the units. Before you starting to solve, you should check the units and understand that correctly.\n\nLet's solve the question. \n\n100m/s to km/h;\nif we travel 100m in 1 second then we travel (3600*100)m in a hour. \n!!!Because 1 hour is equal to 3600 seconds.!!!(Eq.1)\n\n360000m is equal 360km. \n\n!!!Because 1000m is equal 1km.!!!(Eq.2)\nSo your first question's answer is 360km/h\n\nNow, using the information above we convert 60km/h to m/s.\nWell, 60 km is equal 60000m. (Eq.2)\n60000/3600= 16,67m/s (Eq.1)\n\nLet me ask a question. What is the 717 miles/h in m/s?
