Dear Sourav
Speed = 45 km/hr
Means
In 1 hour or 60 kinutes it travels 45 km
Hence in 30 mins it will travel 45/2 = 22.5 Km

Speed = 45 KM/HR.
1 hour = 60 mins = 45 Kms
30 mins= 45/2
= 22.5 or 22 ½ km per 30 min.
REENU SIVADARSHINI.M
speed =45km/ hr ; time =1/2 hr
distance = speed * time
distance =45/2=22.5 km
so therefore the distance travelled is 22.5 km with 45 km /hr speed in ½ an hour

The car goes 45km in 1 hour or 60 min.
Hence it goes 45/2=22.5km in 60/2=30 min.
