Two hikers are walking along the appalachian trail. the first hiker is 2 miles ahead of the second hiker. both hikers are traveling in the same direction at the same speed, 1 mile per hour. let x represent the distance traveled by the first hiker after a certain time period.
several students wrote equations for this situation. which student is correct?
a.
alex said, “the equation y = 2x + 1 represents the total distance traveled by both hikers.”
b.
brenda said, “the equation y = 3x represents the total distance traveled by both hikers.”
c.
chris said, “the equation y = x – 2 represents the distance traveled by the second hiker.”
d.
drake said, “the equation y = x + 2 represents the distance traveled by the second hiker.”
