The problem does not provide any equation or function to find the velocity directly. Therefore, we can estimate the velocity at x=1 using the slope of the line passing through the point (0,0) and (1,11ebb6d7_48cc_6315_b437_3b625c7f031d_TB8593_11).
Slope = (11ebb6d7_48cc_6315_b437_3b625c7f031d_TB8593_11 - 0) / (1 - 0) = 11ebb6d7_48cc_6315_b437_3b625c7f031d_TB8593_11
Velocity at x=1 is equal to the slope, which is approximately 16 ft/s. Therefore, the best choice is option C.
