SAT Mathematics Practice Test 3

Marilyn’s distance from her campsite remained the same during the time she ate lunch.
This is represented by a horizontal segment in the graph. The only horizontal segment in the graph starts at a time of about 1:10 p.m. and ends at about 1:40 p.m.
Therefore, Marilyn finished her lunch and continued her hike at about 1:40 p.m
Choices A, B, and D are incorrect and may be the result of a misinterpretation of the graph.
For example, choice B is the time Marilyn started her lunch, and choice D is the time Marilyn was at the maximum distance from her campsite.
