It’s given that t represents the number of seconds after the =30 bus passes the marker. Substituting 2 for t in the given equation d t yields =30 2 =60 60 d ^ h, or d . Therefore, the bus will be feet from the marker 2 seconds after passing it. Choice A is incorrect. This is the distance, in feet, the bus will be from the marker 1 second, not 2 seconds, after passing it. Choice B is incorrect and may result from conceptual or calculation errors. Choice D is incorrect. This is the distance, in feet, the bus will be from the marker 3 seconds, not 2 seconds, after passing it.</p>","correct_answer":["C"],"has_media":false,"has_mathml":false,"has_table":false,"source_created_at":null,"source_updated_at":null,"options":[{"label":"A","content_html":"<p>30</p>","ord":0},{"label":"B","content_html":"<p>32</p>","ord":1},{"label":"C","content_html":"<p>60</p>","ord":2},{"label":"D","content_html":"<p>90</p>","ord":3}],"attribution":{"source_id":"cb_practice_pdf","source_name":"College Board full-length SAT practice tests (PDF)","rights_holder":"College Board","canonical_url":"https://satsuite.collegeboard.org/practice/practice-tests/paper","retrieved_from":"https://satsuite.collegeboard.org/practice/practice-tests/paper","attribution":"Full-length SAT practice tests 4–11 © College Board, published free at satsuite.collegeboard.org.","disclaimer":"Extracted from PDF layout: equations, figures and tables do not survive intact.
