The average rate of the first part of yi’s walk on a park loop was 4 miles per hour. she then met up with a friend and the two walked the rest of the way at an average rate of 5 miles per hour. the entire 3-mile walk took yi 42 minutes (0.7 hour). which equation can be used to solve for x, the time in hours that yi spent walking before meeting her friend? x = 0.7 – x x + (0.7 – x) = 1 4x + 5(0.7 – x) = 1 4x + 5(0.7 – x) = 3
