Answer 2

Calculation of Fuel Consumption

To calculate the fuel consumption of the engine, we need to know the fuel consumption rate per hour. According to the information provided, the engine consumes 2.5 liters of gasoline per hour.

Fuel Consumption on the First Day

On the first day, the engine worked for 4 hours. To calculate the fuel consumption on the first day, we multiply the fuel consumption rate per hour by the number of hours the engine worked:

Fuel consumption on the first day = 2.5 liters/hour * 4 hours = 10 liters of gasoline.

Fuel Consumption on the Second Day

On the second day, the engine worked for 5 hours. To calculate the fuel consumption on the second day, we use the same formula:

Fuel consumption on the second day = 2.5 liters/hour * 5 hours = 12.5 liters of gasoline.

Fuel Consumption over Two Days

To calculate the total fuel consumption over the two days, we add the fuel consumption on the first day and the fuel consumption on the second day:

Total fuel consumption = Fuel consumption on the first day + Fuel consumption on the second day = 10 liters + 12.5 liters = 22.5 liters of gasoline.

Therefore, the engine consumed 22.5 liters of gasoline over the course of two days.

Please note that the information provided is based on the assumption that the fuel consumption rate remains constant throughout the operation of the engine.
