we know that
speed=distance/time
here speed is 120 km/hr i.e120000m/3600sec
for 3600 sec it will cover 120000 m
therefore for 30 sec it will cover=120000/3600*30
i.e.100 m
speed=distance/time
here speed is 120 km/hr i.e120000m/3600sec
for 3600 sec it will cover 120000 m
therefore for 30 sec it will cover=120000/3600*30
i.e.100 m

speed = 120 km/hr = 120 * 5/18 m/sec
distance covered in 30 s = 120 * 5/18 * 30 m = 1000 m or 1 km
distance covered in 30 s = 120 * 5/18 * 30 m = 1000 m or 1 km
