Final answer:
Alicia is 45 miles away from city B if the two cities are 45 miles apart and Alicia lives in city A.
Step-by-step explanation:
The total length of the actual path followed by an object is called as distance. The straight line (shortest) distance between two points, directed from one position to other is called as displacement of an object between those positions. SI unit to measure distance and displacement is meter (m).
If cities A and B are 45 miles apart and Alicia lives in city A, then Alicia is 45 miles away from city B. This is a straightforward distance measurement and does not require any additional information or calculations.
When measuring distance between two locations, the most important factors are the starting point, the ending point, and the path taken between them.
Since a direct path is given between city A and city B, the distance mentioned is the actual distance.
