The low fuel warning light came on when 11 L of gas was left in the tank. If Lindsay's vehicle uses gas at the rate of 9.3 L/100 km, estimate when the warning light came on. \n" ); document.write( "

At 9.3L per 100km, the number of km she drove before the light came on was \r\n" ); document.write( "\r\n" ); document.write( " 100km\r\n" ); document.write( " 20 L * ------- = 215 km (to the nearest whole number)\r\n" ); document.write( " 9.3L \n" ); document.write( "Since she drove at 100 km/h, her driving time, from her start at 1:30 pm to when the light came on, was 2.15 hours, or 2 hours 9 minutes. \n" ); document.write( "ANSWER: The warning light came on at about 3:39 pm. \n" ); document.write( " |
