Question

distance vs. time graphs

1. choose the correct description.

jackie left her house for a jog. her workout alternated between running for 1.5 minutes and walling for 1.5 minutes. she stopped after 0.7 miles to rest at a park.
paisley drove to her friend’s house to go study with her for an upcoming test. it normally takes her five minutes to get to her friend’s house. today, however, she got stopped by a train for two minutes when she was halfway to her friend’s house.
nathan ran after his dog that got out for over half a mile before he caught him. he rested with the dog for several minutes before slowly walking home.

Explanation:

Step1: Analyze Graph 7 features

Graph 7 shows increasing distance with multiple speed changes (slope variations) and no decrease (no return home), ending with a flat segment (rest).

Step2: Match to descriptions

Jackie’s description: alternates running/walking (slope changes), stops at 0.7 miles (flat segment) – matches Graph7.
Paisley’s: stopped halfway (one flat segment, no multiple speed changes) – no.
Nathan’s: returns home (distance decreases) – no.
