Suppose you have to walk for 4.87 km to attend a party at your friend's home. If you have already walked for 1500 m twice, how many more kilometres do you have to go?
1.37 km
4.87 km = 4.87 × 1000 = 4870 m
Metres covered = 1500 × 2 = 3000 m
No. of meters left to go = 4870 - 3000 = 1870 m
1870 m = 13701000 = 1.87 km
