Input interpretation
anti-knock index
Equation
AKI = (RON + MON)/2 | AKI | anti-knock index RON | research octane number MON | motor octane number
Input values
research octane number | 91 motor octane number | 83
Results
anti-knock index | 87
Possible intermediate steps
Calculate the anti-knock index using the following information: known variables | | RON | research octane number | 91 MON | motor octane number | 83 The relevant equation that relates anti-knock index (AKI), research octane number (RON), and motor octane number (MON) is: AKI = (RON + MON)/2 Substitute known variables into the equation: known variables | | RON | research octane number | 91 MON | motor octane number | 83 | : AKI = (91 + 83)/2 Evaluate (91 + 83)/2: Answer: | | AKI = 87
