The total number of seconds the trip took is

31*3600+27*60+49 = 113269

The total number of seconds spent refueling is

8*3600+48*60+8 = 31688

Therefore, the percentage of time spent in the air is

100*(113269-31688)/113269 = 72.0241%.

• First turn everything in to seconds, and divide.

31h 27min 49s = 113,269 seconds

8h 48min 8s = 31,688 seconds

Subtract out the ground time

113,269 seconds - 31,688 seconds = 81,581 seconds in the air

divide air seconds by total seconds

81,581 / 113,269 = 0.720241195738

Convert to % by multiplying by 100 = 72.0241195738 %
