some part of a journey of 780 km was made by a car with speed of 60 km per hour and the remaining journey was made by train with a the speed of 100 km per hour.if the total time required was 9 hours find the time taken by train and distance covered by train
\n" ); document.write( "

Let time taken by train be T
\n" );
document.write( "Then we get the following DISTANCE equation: 
\n" );
document.write( "Solve this for T, the time traveled by train
\n" );
document.write( "Multiply value of T by 100 to get distance traveled by train\r
\n" );
document.write( "\n" );
document.write( "OR\r
\n" );
document.write( "\n" );
document.write( "Let distance by train be D
\n" );
document.write( "Then we get the following TIME equation: 
\n" );
document.write( "Solve this for D, the distance by train
\n" );
document.write( "Divide value of D by 100 to get time taken to travel by train \n" );
document.write( "

\n" );
