Expert Answer

Let R be the radius of semi-circular path as shown in figure.
 
Displacement in semi circular path is diameter (d)= 2R
distance covered in semi circular path = R
 
It is given that the distance covered by the body to complete semicircular path is 5 m
This means, 
distance, 5 = R
Hence, 
R = 5/ ... (1) 
 
Now, 
displacement = 2R = 2( 5/) = 10/
 
ratio of distance covered to displacement is,
