Question

24.375 kilometres of road in a panchayat needs tarring. Of this, 18.43 kilimetres has been tarred. How much more remains to be tarred?

Answer 1

Length of the panchayat road that needs tarring = 24.375 km

Length of the panchayat road that has been tarred = 18.43 km

These lengths can also be written as:

24.375 km = 24 km + 375 m

18.43 km = 18 km + 43 m

Length of the panchayat road that remains to be tarred = Length of the panchayat road that needs tarring − Length of the panchayat road that has already been tarred

∴ Length of the panchayat road that remains to be tarred = (24 km + 375 m) − (18 km + 43 m)

		km		m
		24		375
−		18		430
		05		945

The length of the panchayat road that remains to be tarred is 5 km and 945 m, i.e. 5.945 km.
