Answer 1

Answer:

Step-by-step explanation:

74 +  97 = 171 mm

Length of the train track = 171 mm = 171÷ 1000 = 0.171 m

Answer 2

Answer:

0.171 m

Step-by-step explanation:

First, let's determine how many mm of track he has in total...

74mm+97mm=171 mm

Now, we can set up a unit converter to convert mm to m (note that 1 mm is $10^{-3{$ m)...

$171mm(\frac{10^{-3}m}{1mm})$

The "mm" cancels out...

$171*10^{-3}m=0.171m$
