Answer:

89 km 720 m less than 120 km 180 m is 30 km 460 m

Step-by-step explanation:

Given

89km 720 m $= 89+\frac{720}{100} km\\\\=89+0.72 km\\\\=89.72 km$

120 km 180 m

$= 120+ \frac{180}{100} km\\\\= 120+0.18km\\\\=120.18km$

89.72 km less than 120.18 km

= 120.18- 89.72

=30.46 km

That is 30 km 460 m
