a car leaves town a for town b, which are 550 km apart, at an average speed of 72 km/h.
\n" ); document.write( " at the same time, a truck leaves town b for town a and travels along the same road as the car at an average speed of 38 km/h.
\n" ); document.write( " find the time taken for the two vehicles to meet.
\n" ); document.write( ":
\n" ); document.write( "Let t = time it takes for them to meet
\n" ); document.write( ":
\n" ); document.write( "When the two meet, they will have traveled a total of 550km
\n" ); document.write( ":
\n" ); document.write( "Write a distance equation, dist = speed * time
\n" ); document.write( "then
\n" ); document.write( "72t = car's dist
\n" ); document.write( "38t - truck's dist
\n" ); document.write( ":
\n" ); document.write( "Car dist + truck dist = 550 km
\n" ); document.write( "72t + 38t = 550
\n" ); document.write( "Add like terms
\n" ); document.write( "110t = 550
\n" ); document.write( "t = 550/110
\n" ); document.write( "t = 5 hrs
\n" ); document.write( ":
\n" ); document.write( "Do you understand this now?
