Answer:
0.028578 km
Explanation:
The following data were obtained from the question:
Length of whale (in mm) = 28578 mm
Length of whale (in km) =?
We can convert 28578 mm to km by doing the following:
Recall:
1 mm = 1×10¯⁶ Km
Therefore,
28578 mm = 28578 mm × 1×10¯⁶ Km / 1 mm
28578 mm = 0.028578 km
Thus, 28578 mm is equivalent to 0.028578 km
The length of whale (in km) = 0.028578 km
