Answer 1

Answer:

• B) 83.4 kilometers

Step-by-step explanation:

According to table we have units:

• Kilo = 1000     ⇒ km = 1000 m
• Milli = 0.001   ⇒  mm = 0.001 m

Comparing the two units we can see that:

• 1  Km = 1000/0.001 = 1000000 mm

Then we can convert the distance in mm to Km:

• 83400000 mm =
• 83400000 / 1000000 km =
• 83.4 km

Correct choice is B
