1hr = 3600 secs
3600sec = 180km
1sec = 180/3600km
30sec = 180*30/3600 km
=1/2 km
3600sec = 180km
1sec = 180/3600km
30sec = 180*30/3600 km
=1/2 km

Solution:-
man running speed = 180km/h
= 180×5/18 = 10×5 = 50m/s
man covered distance in 30 secound = 30×50
= 1500m = 1.5km
man running speed = 180km/h
= 180×5/18 = 10×5 = 50m/s
man covered distance in 30 secound = 30×50
= 1500m = 1.5km
