Answer:
22.86%
Step-by-step explanation:
To get the overall efficiency of the process, we simply get the product of the given efficiencies.
Therefore, overall efficiency of the process=Crude production efficiency* Transportation efficiency* Refining efficiency* Distribution of gasoline efficiency* Engine efficiency efficiency
Overall efficiency=0.93*0.92*0.94*0.97*0.293*100%=22.85798714 %
Approximately, the overall efficiency of the process is 22.86%
