Select the correct answer. Lucian and Blake are taking their bikes out to a nature trail in the woods. They want to be out for no more than 6 hours, and they want to travel at least 40 miles between walking and biking. On average, they walk at a rate of 3 miles/hour and bike at a rate of 12 miles/hour. Which graph represents the number of hours Lucian and Blake can spend either walking or biking to meet their goals? A. Walking and Biking graph, a line intercepts the x and y-axis at 6 units and another line intercepts the y-axis at 3.2 units. Both intersect at (3.8, 2.2) with a dark shaded region on the right side, and lightly shaded on the upper and lower sides B. Walking and Biking graph, a line intercepts the x and y-axis at 6 units and another line intercepts the y-axis at 3.2 units. Both intersect at (3.8, 2.2) with a dark shaded region on the lower side, and lightly shaded on the left and right sides C. Walking and Biking graph, a line intercepts the x and y-axis at 6 units and another line intercepts the y-axis at 3.2 units. Both
