<gadget id="calculator">5350*2</gadget>
<output>10_700</output>
10700 steps were made when he run twice the field.
Since he has run half of the field 5350 / 2 = 
<gadget id="calculator">5350/2</gadget>
<output>2_675</output>
2675 steps were made when he runs half of the 3-kilometer field.
Therefore, Charlie was able to make 10700 + 2675 = 
<gadget id="calculator">10700+2675</gadget>
<output>13_375</output>
13375 steps for the 2 and a half run around the field.
