A train running at the speed of 90 km/hr crosses a platform of length 160 m in 10 seconds. What is the length of the train (in meters)?
\n" ); document.write( "------
\n" ); document.write( "Convert 90km/hr to meter per sec.
\n" ); document.write( "---
\n" ); document.write( "90km/h(1h/3600sec)(1000m/1km) = 25meter/sec
\n" ); document.write( "---
\n" ); document.write( "Find distance the train travels in 10 seconds.
\n" ); document.write( "-------------
\n" ); document.write( "= 250 meter/10sec
\n" ); document.write( "----
\n" ); document.write( "Find length of train:
\n" ); document.write( "length + 160 meters = 250 meters
\n" ); document.write( "The train = 250-160 = 90 meters long
\n" ); document.write( "=====================
