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^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula

probably .5
