But hey co eatap orri nmde sta oo mom i The propare bus operating cost (above and beyond tuel cost) is 27 he propane model vs. 12 mpo for diesel. The life of a school bus in the district averages beter choice based on a life-cydle analysis? el oosts about $5/galion in Geargia, about $1 more than propane.Bus mileage is 13 mpa for a years, and each bus trevels an average of 33,000 miles per year because the district is so large and nural. Which bus is the The toral cost of using one peopane-fusied bus during its ife cycle is s(ound your response to the nsaret o)Explanation / Answer
Fuel cost per mile for propane buses
= Price of Propane per Gallon / Mileage given by Propane per Gallon
= $4/ 13
= 0.3076 $/ mile
= 30.76 cents / mile
Fuel cost per mile for Diesel buses
= Price of diesel per Gallon / Mileage given by diesel per Gallon
= $5/12
= 0.4166 $/ mile
= 41.66 cents/ mile
Operating cost / mile for propane buses = 27 cents
Operating cost / mile for diesel buses = 36 cents
Therefor, fuel plus operating cost per mile for Propane buses = 30.76 cents/ mile + 27 cents/ mile = 57.76 cents/ mile
Fuel plus operating cost per mile for diesel buses = 41.66 cents / mile + 36 cents/ mile = 77.66 cents / mile
Total distance travelled by a Propane bus in a year = 33,000 miles/ year x 8 years = 264,000 mile
Therefore .
Total fuel and operating cost of one propane fuelled bus during the life cycle
= 57.76 cents/ mile x 264,000 miles
= 15248640 cents
= $152486.40
Purchase price for a propane bus = $95,000
Therefore ,
Total cost of using one propane fuelled bus during its life cycle
= Fuel and operating cost during life cycle + purchase coat
= $152486.40 + $95,000
= $247486.40 ( $247486 rounded to nearest whole number )
The total cost of using one propane fuelled bus during its life cycle is $ 247486
The total cost of using one propane fuelled bus during its life cycle is $ 247486
