While hiking, Owen's velocity varied, as shown on the graph below. Find Owen's total distance traveled on the interval left square bracket 1 comma space 5 right square bracket. A graph with an x-axis representing time in hours and a y-axis representing velocity in miles per hour and ranging from 0 to 6. A line slants upward from the origin (0, 0) to the point (1, 1) and then continues horizontally until the point (2, 1). From this point, the line slants upward to the point (3, 3) and continues horizontally until the point (4, 3). The line then slants downward to meet the x-axis at (5, 0). A.) 7.5 miles B.) 6 miles C.) 8 miles D.) 7 miles
