Final answer:
The average flow rate of gasoline to the engine of a car traveling at 115 km/h with a fuel efficiency of 12 km/l is 2.662 cm³/s. The provided multiple-choice options do not match the calculated flow rate.
Step-by-step explanation:
To calculate the average flow rate in cm³/s for a car traveling at 115 km/h with a fuel efficiency of 12 km/l, we can use the following method:
- First, convert the speed from km/h to m/s: 115 km/h * (1000 m/km) / (3600 s/h) = 31.944 m/s.
- Then, calculate the fuel consumption rate in liters per second: Speed (m/s) / fuel efficiency (km/l) * (1 km / 1000 m). So, 31.944 m/s / (12 km/l) * (1 km / 1000 m) = 0.002662 L/s.
- Convert the fuel consumption rate to cm³/s by using the conversion 1 L = 1000 cm³. Therefore, the flow rate is 0.002662 L/s * 1000 cm³/L = 2.662 cm³/s.
Since none of the options provided (a. 2.87 x 10⁶ cm³/s b. 3.21 x 10⁶ cm³/s c. 3.46 x 10⁶ cm³/s d. 3.79 x 10⁶ cm³/s) matches the calculated flow rate, there might have been an error in the question or a misunderstanding of the values required to calculate the flow rate.
