1 km = 1000m
Therefore , 10 km = 10000 m
For 10000 m , 1 litre is needed
Therefore for 1 m , 1/10000 litre is needed
Thus for 900 m , 1/10000 ×900 litre will be needed
1/10000 ×900
= 9/100
= 0.09 litre
Therefore , 10 km = 10000 m
For 10000 m , 1 litre is needed
Therefore for 1 m , 1/10000 litre is needed
Thus for 900 m , 1/10000 ×900 litre will be needed
1/10000 ×900
= 9/100
= 0.09 litre
