Naresh walked 2 km 3m in the morning and 1km7m in the evening. How much distance did he walk in all?
We know that 1000 m=1 km
1m=11000 km
So,
∴1 m = 11000 km\therefore 1~m~=~\frac{1}{1000}~km
2 km 35 m =2 km + 35 m= 2 km + 1 m×35 =2 km + 11000 km ×35 = 2.035 km
1 km 7 m =1 km + 7 m= 1 km + 1 m×7 =1 km + 11000 km ×7 = 1.007 km
Distance travelled in morning =2 km 35 m=2.035 km
Distance travelled in evening =1 km 7 m=1.007 km
