You can put this solution on YOUR website!
Let r = the safe ascent rate (30 feet per min.)
\n" ); document.write( "We know that rate = distance/time
\n" ); document.write( "Distance, d = 165 feet
\n" ); document.write( "To get the time required to travel a certain distance, invert the rate and multiply by the distance.
\n" ); document.write( "Thus we have t = d/r
\n" ); document.write( "Putting in the numbers gives t = 165 feet/(30 feet/min) = 5.5 min.
\n" ); document.write( "Ans: 5.5 minutes
\n" ); document.write( "
