If the lake is 69 km wide, Sheila leaves at 1 pm, and May leaves at 1:15pm, what time will they meet? Please solve step by step and explain. Thanks \n" ); document.write( "
Algebra.Com's Answer #472265 by josgarithmetic(39625) ![]() You can put this solution on YOUR website! The sum of their distances when they meet will be 69 km. Do you want to focus on a number line, or do you want to focus on time quantity? \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Try looking at time quantity. May travels less time than Sheila, because May began her trip LATER than Sheila. Note that the difference between 1 pm and 1:15 pm is (1/4) of an hour. ... THINK how this seems correct. \n" ); document.write( "... \n" ); document.write( "Let h = time that May travels. This means that h+1/4 is the time in hours that Sheila travels. ..., again, THINK how this seems correct. \n" ); document.write( "... \n" ); document.write( "READY?\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Make a data table.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Rower_________speed,km/hour ______time__________distance, km. \n" ); document.write( "Sheila_________12________________h+1/4_________ \n" ); document.write( "May____________10_________________h_____________ \n" ); document.write( "TOTAL___________________________________________ \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Can you study all that and understand the process?\r \n" ); document.write( "\n" ); document.write( "Can you use the information in the data table and see the equation to form?\r \n" ); document.write( "\n" ); document.write( "Can you solve the equation for h? \r \n" ); document.write( "\n" ); document.write( "Finally, use h to get the time of the day that they meet? \n" ); document.write( " |
