    Answer:

    3.008 km or 3.0 km

    Step-by-step explanation:

    According to the Pythagoras theorem:

     {c}^{2}  =  {a}^{2}  +  {b}^{2}  \\  \therefore \:  {a}^{2}  =  {c}^{2}  -  {b}^{2}  \\ \therefore \:  {a}^{2}  =  {(9.3)}^{2}  -  {(8.8)}^{2} \\  \therefore \:  {a}^{2}  =  {(9.3 + 8.8)}{(9.3 - 8.8)} \\ \therefore \:  {a}^{2}  =  18.1 \times 0.5 \\  \therefore \:  {a}^{2}  = 9.05 \\ \therefore \:  {a}  =  \sqrt{9.05}  \\ \therefore \:  {a}  =  3.00832179 \\ \therefore \:  {a}  = 3.0 \: km
