two cars leave a crossroads at the same time. One heads north at 50km/h and the other heads east at 70km/h. How far apart art the cars after 0.5h? After 2h?
\n" ); document.write( "..
\n" ); document.write( "it means that they are taking a right angle path.
\n" ); document.write( "\"+Distance+=+rate+%2A+time\"
\n" ); document.write( "car 1 rate = 50km/h
\n" ); document.write( "time = 0.5 hours
\n" ); document.write( "Distance = 50*0.5 = 25 km.
\n" ); document.write( "..
\n" ); document.write( "Car 2 rate = 70km/h
\n" ); document.write( "distance = 70*0.5 = 35km.
\n" ); document.write( "35 km and 25 km are the legs of right triangle
\n" ); document.write( "\"35%5E2%2B25%5E2=+D%5E2\"
\n" ); document.write( "1225+625=D^2
\n" ); document.write( "\"D%5E2=1850\"
\n" ); document.write( "\"+D+=+sqrt%281850%29\"
\n" ); document.write( "D= 43.01 km.
\n" ); document.write( "..
\n" ); document.write( "repeat the same for 2h time
\n" ); document.write( "
\n" );
