This is a proportional reasoning calculation. You will want to set up equations, but mostly to look at how the orbital distance affects the orbital velocity, or to set up a ratio. (Once you know how it changes you'll have to multiply by the value at the surface to get an answer in m/s.) At the surface of the exoplanet G 9-40 b, the orbital velocity would be 1.21E+4 m/s. What would the orbital velocity be 11 radii above the surface? m/s. Note: If your answer requires scientific notation, remember that OWL uses "e" notation: 1.1 x 105 is 1.1e5 to OWL.
