You can put this solution on YOUR website!
At the start your speed is 0 km/hr. After moving and accelerating for 5 seconds your speed is 60 km/hr. Acceleration is [change in rate] divided by [change in time]. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Here the units are changed first to seconds instead of hours, but your purposes may justify not other time units.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(60 km/hour) * (1 hour/60 min) * (1 min/60 sec) = 1/60 km/sec\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Look at the data.
\n" ); document.write( "final rate = 1/60 km/sec
\n" ); document.write( "initial rate = 0 km/sec
\n" ); document.write( "final time = 5 sec
\n" ); document.write( "initial time = at 0 sec\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Acceleration = \"%281%2F60-0%29%2F%285-0%29=%281%2F60%29%2F5\"
\n" ); document.write( "=\"5%2F60\"=\"highlight%281%2F12%29\", in units of \"highlight%28km%2Fs%5E2%29\"
\n" ); document.write( "
\n" );
