Algebra.Com's Answer #291979 by htmentor(1343)![]() ![]() 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( " \n" ); document.write( " |
