Algebra.Com's Answer #507159 by josgarithmetic(39799) ![]() You can put this solution on YOUR website! This data table indicates both how the variable, t, is assigned and the expressions for the distance. The times and t are in time QUANTITIES, not as time points on a cock or number line. Just recall that the question is for the TIME ON THE CLOCK, A POINT OF TIME OF THE DAY, so you'll need to make the appropriate adjustment computation after solving for t.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "_________________speed____________time___________distance \n" ); document.write( "Rae______________12_______________t+2____________d=12(t+2) \n" ); document.write( "Myra_____________18________________t_____________d=18t\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "There is a lesson for this form of travel problem: \n" ); document.write( "http://www.algebra.com/tutors/Uniform-Rates-Travel%3A-same-direction-but-different-travel-times-meet-when%3F.lesson?content_action=show_dev \n" ); document.write( " |
