The 2 sides and the diagonal of the rectangle form the 3 sides of a right
\n" ); document.write( "triangle, with the diagonal being the hypotenuse.
\n" ); document.write( "To find the measure of the diagonal, we can use the Pythagoras theorem.
\n" ); document.write( "Diagonal = sqrt(80^2 + 60^2) = sqrt(10000) = 100 m
\n" ); document.write( "He runs at 9 m per sec.
\n" ); document.write( "Time = Distance / speed = 100/9 = 11.11 sec
\n" ); document.write( "Hope you got it :)
\n" ); document.write( " \n" ); document.write( "
