Since they are travelling in opposite directions, it is like one car going at the sum of the two speeds or
\n" ); document.write( "(1) d = (r1 + r2)*t or using the values you are given
\n" ); document.write( "(2) 330 = (60 + 50)*t or
\n" ); document.write( "(3) 330 = 110*t which gives
\n" ); document.write( "(4) t = 330/110 or
\n" ); document.write( "(5) t = 3
\n" ); document.write( "Lets check this value of time by calculating the distance each car travels in 3 hours.
\n" ); document.write( "(6) d1 = 60*3 or
\n" ); document.write( "(7) d1 = 180 mi
\n" ); document.write( "and
\n" ); document.write( "(8) d2 = 50*3 or
\n" ); document.write( "(9) d2 = 150 mi
\n" ); document.write( "Is (d1 + d2 = 330)?
\n" ); document.write( "Is (180 + 150 =330)?
\n" ); document.write( "Is (330 = 330)? Yes
\n" ); document.write( "Answer: The cars will 330 miles apart at 1:00 pm the same day.
