Question

The graph shows the relationship between the number of hours that Michelle has been driving and the distance that she has left to travel to get to her destination.

A graph on a coordinate plane titled Distance Remaining Over Time. The x-axis is labeled time (in hours), numbered 1 to 8, and the y-axis is labeled miles to destination, numbered 50 to 400. A straight line with a negative slope starts at point (0, 350) and ends at point (7, 0).

Which statement is true?

It took Michelle 6 hours to complete the trip.
For each hour that Michelle drove, she traveled an additional 50 miles.
In the first 6 hours, Michelle had traveled a total of 50 miles.
In the first 3 hours, Michelle had traveled a total of 200 miles.

Answer 1

True statement: "For each hour that Michelle drove, she traveled an additional 50 miles."

Reason: The line goes from (0, 350) to (7, 0), so the change in distance is 350 miles over 7 hours → 350/7 = 50 miles per hour. Thus each hour she drives she covers 50 miles.
