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