Train A leaves the station traveling east at 55 mph
\n" ); document.write( " while train B leaves the station 45 minutes later traveling west at 70 mph.
\n" ); document.write( " Choose the equation below that represents the distance in miles between the two trains, D, as a function of T, the time in hours after train B has departed
\n" ); document.write( ":
\n" ); document.write( "Change 45 min to .75 hrs
\n" ); document.write( "Distance = speed * time
\n" ); document.write( "Train A's distance = 55(t+.75)
\n" ); document.write( "Train B's distance = 70t
\n" ); document.write( "The equation
\n" ); document.write( "D(t) = 70t + 55(t+.75)
\n" ); document.write( "
