500 cm 500 m 1:2000 000

2)

Solution: Assume that the actual distance from Beijing to Harbin is X cm.

3.5÷X= 1÷35000 000

3.5×35000 000= 1X

X= 122500 000

122500 000cm= 1225km

3)

12000 000 cm = 120 km

31×120 = 3720km.

A: _ _.

4)

Length: 6× 20 000 = 120 000 cm = 1.2 km.

Width: 3× 20 000 = 60 000 cm = 0.6 km.

A: _ _.

1.2×0.6=0.72km？

A: _ _.

5)

400 000 cm = 4 km

4×9 = 36 km

36÷60 = 0.6 hours

A: _ _.

6)
