3 Calculate the total distance, in m, that Aiman travelled to
school for 5 days on a round-trip.
10 × 2.735 km = m
10 × 2.735 km = 10 × (2.735 × 1 000) m 2.735 km

= 10 × 2 735 m
= 27 350 m

10 × 2.735 km = 27 350 m

The total distance that Aiman travelled to school for
5 days on a round-trip is 27 350 m.

= 4 850 m = 19 800 cm
= (4 850 ÷ 1 000) km = (19 800 ÷ 100) m
= 4.850 km = 198 m
