Let's do it the long way first. We need to convert the hours to minutes. 3hr= 180 minutes. 180+30= equals 210 minutes. So now we can rewrite it as : The car travels 196 miles in 210 minutes. \r
\n" ); document.write( "\n" ); document.write( "Distance/Time= Velocity\r
\n" ); document.write( "\n" ); document.write( "196/210= 0.93 miles/min. \r
\n" ); document.write( "\n" ); document.write( "Now we multiply 0.93 x 60 because there are 60 minutes in a hour. That will tell us how many miles per hour the car is traveling. So 0.93333333x60= 56.0 mph\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now let's do it the short and easier way: we still use the same equation: Distance/Time= Velocity.\r
\n" ); document.write( "\n" ); document.write( "Only this time we will simply convert the 3 hours and 30 minutes into hours which is easy enough. 3 hours and 30 minutes= 3.5 hours obviously.\r
\n" ); document.write( "\n" ); document.write( "So now:
\n" ); document.write( "Distance(196)/Time(3.5)= 56 miles/hr.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The long way is a headache but will give you good practice at converting numbers for equations which you will have to do ALOT as you move on in mathematics education.\r
\n" ); document.write( "\n" ); document.write( "Hope this helps!\r
