(6) Sunita travelled 15 km 268 m by bus, 7 km 7 m by car and 500 m on foot in order to reach her school. How far is her school from her residence?

Solution: here, 15 km 268 m = 15.268 km; 7 km 7 m = 7.007 km and 500 m = 0.5 km

Therefore, the total distance that Sunita covered = (15.268 + 7.007 + 0.5) km = 22.775 km

(7) Ravi purchased 5 kg 400 g rice, 2 kg 20 g sugar and 10 kg 850g flour. Find the total weight of his purchases.
