Sam and Liam raced each other up and then down the hill. Sam's average speed up the hill was 1 mph, and his average speed down was 9 mph. Liam ran up the hill and down the hill with the same speed, 2 mph. If the path from the bottom to the top of the hill is 1 mile long, how much time did it take each of the boys to finish - and who was the winner?

When constructing a perpendicular line through a point off a line, how can you verify that the lines constructed are perpendicular? check the angles used in the construction with a straightedge to ensure consistency. check the distance along the lines at several places with a compass to ensure they are the same length. check the intersecting lines with the corner of a piece of paper to ensure the lines create 90° angles. check the distance between the lines at several places with a compass to ensure they are equidistant. question 2(multiple choice worth 1 points) (01.03 lc) which of the following steps is included in the construction of a perpendicular line through a point on a line? connect arcs that are above and below the given line with a straightedge. connect arcs that are above the original line with a straightedge. create arcs on either side of a point that is off the given line. create a copied angle by using the first two lines as the original angle.
