If the alternator-to-engine drive ratio is 2.65 to 1 , what rpm will the alternator have when the engine is idling at 300 rpm ? Hint: Use a direct proportion. The alternator will have \( \square \mathrm{rpm} \) when the engine is idling at 300 rpm . (Type a whole number or a decimal.)

To find the rpm of the alternator when the engine is idling at 300 rpm, we can set up a direct proportion based on the drive ratio. The formula for this calculation is: \[ \text{Alternator RPM} = \text{Engine RPM} \times \text{Drive Ratio} \] So, with a drive ratio of 2.65: \[ \text{Alternator RPM} = 300 \, \text{rpm} \times 2.65 \approx 795 \, \text{rpm} \] The alternator will have 795 rpm when the engine is idling at 300 rpm.
