= (2.25 × 1 000) m ÷ 10

= 2 250 m ÷ 10
= 225 m

The distance of the resurfaced road
in 1 hour is 225 m.

5 238.9 km ÷ 100 = m 6 30 m 72 cm ÷ 1 000 = cm
238.9 km ÷ 100 = 2.389 km 30 m 72 cm = (30 × 100) cm + 72 cm

= (2.389 × 1 000) m = 3 000 cm + 72 cm
= 2 389 m = 3 072 cm

238.9 km ÷ 100 = 2 389 m 3 072 cm ÷ 1 000 = 3.072 cm

30 m 72 cm ÷ 1 000 = 3.072 cm

2 Complete these.
a 48.3 km ÷ 10 = km

b 48.3 km ÷ 100 = m

3 Divide the following. State the answer in m.
a 3.672 km by 18. b 32 m 10 cm by 100.
