Question 3 (1 point) What are the best units for a scientist to measure the distance between cities?
A. miles
B.inches
C.meters
D.kilometers

A and D

Explanation: Miles and Kilometers are the best units when measuring distances between cities, this is because both units will in most cases give a reasonable representation of the distance being measured by giving an output which isn't too large or extremely small. Feets and inches are usually adopted when measuring length of objects which in most cases are small and average only a few meters. Meters are also used for measuring short and medium distances. However, representing distances between two cities in terms of inches or feets will usually give extremely large values. Hence, the need for a fairly larger unit in miles or kilometers.
