Rohan covers 208 m in 14 steps
distance covered by him in 1 step = 280 cm/14
                                                  =20
thus he cover 20 cm s in 1 step 
so distance covered by him in 150 steps=150×20
                                                         =3000 cms 
therefore
 he covers 30 m in 150 steps
