Question

keisha told her friend that she can get to the town library by walking one mile east, turning left, and then walking a half a mile north.
which best describes how keisha can improve these instructions to better help her friend find the library?
using meters as the unit instead of miles
drawing a picture of the library on a line diagram
estimating the amount of time to get to the library
providing a reference point

Explanation:

The current instructions lack a starting point, so the friend has no reference to begin the journey. Changing units, drawing a library picture, or estimating time does not fix the core issue of no initial reference. Providing a reference point (like a starting landmark) gives the friend a clear beginning to follow the directions.

Answer:

providing a reference point
