Ms. Simon drives her car from her home to her workplace every workday morning. The table above shows the distance, in miles, and her average driving speed, in miles per hour (mph), when there is no traffic delay, for each segment of her drive.

If Ms. Simon starts her drive at 6:30 a.m., she can drive at her average driving speed with no traffic delay for each segment of the drive. If she starts her drive at 7:00 a.m., the travel time from the freeway entrance to the freeway exit increases by 33% due to slower traffic, but the travel time for each of the other two segments of her drive does not change. Based on the table, how many more minutes does Ms. Simon take to arrive at her workplace if she starts her drive at 7:00 a.m. than if she starts her drive at 6:30 a.m.? (Round your answer to the nearest minute.)

### In the *xy*-plane, line passes through the points (0, 1) and (1, 4). Which of the following is an equation of line ?

**Note: **

The points on a line in the xy-plane always satisfy the equation of the line. Here, notice that both (0, 1) and (1, 4) satisfy the equation y=3x + 1 . So, an alternate way of doing this problem is to check which equation in the options is satisfied by the given points.
