Algebra.Com's Answer #389415 by dragonwalker(73)![]() ![]() ![]() You can put this solution on YOUR website! well, you are traveling at 11 mph. This means that in one hour you travel 11 miles.\r \n" ); document.write( "\n" ); document.write( "So how many 0.5 miles in 11 miles? 11/0.5 = 22\r \n" ); document.write( "\n" ); document.write( "So in one hour you could travel 0.5 miles 22 times. So to travel it once you have to divide one hour by 22 to find how long it takes to travel one of these 0.5 miles.\r \n" ); document.write( "\n" ); document.write( "But you want to know how many seconds, so instead of dividing one hour by 22 you should find how many seconds in an hour and then divide that by 22 instead.\r \n" ); document.write( "\n" ); document.write( "So how many seconds in 1 hour?\r \n" ); document.write( "\n" ); document.write( "Well there are 60 seconds in one minute and then 60 minutes in one hour, so to find how many seconds you have to multiply the number of minutes in one hour by the number of seconds in one minute i.e. 60 x 60 = 3600\r \n" ); document.write( "\n" ); document.write( "So 3600 seconds in one hour divided by how many 0.5 miles are traveled (i.e. 22)\r \n" ); document.write( "\n" ); document.write( "so 3600/22 = 163.64 seconds. Rounded up to 164 seconds to travel 0.5 miles.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
