Challenge Problems

Push your limits with challenges.

Question 1

A company operates a fleet of diesel and gasoline engines. If the diesel engines use 0.04 gallons per horsepower-hour for 8 hours daily, while gasoline ones use 0.06 gallons, calculate the total fuel cost per week if the diesel fuel costs $3.00 per gallon and gasoline costs $3.50.

💡 Hint: Calculate daily costs and extend it to the week.

Question 2

An excavator needs an average of 0.25 liters per horsepower per hour at 300 horsepower. Assess how much lubricant it will need in 10 hours of operation, and at what cost if the lubricant is priced at 25 rupees per liter.

💡 Hint: Break down into hourly consumption and scale up.
