Answer : The percentage error was, 15.6 %.
Step-by-step explanation :
To calculate the percentage error, we use the equation:
[tex]\%\text{ error}=\frac{|\text{Experimental value - Accepted value}|}{\text{Accepted value}}\times 100[/tex]
We are given:
Experimental value = 74 minutes
Accepted value = 64 minutes
Putting values in above equation, we get:
[tex]\%\text{ error}=\frac{|74-64|}{64}\times 100\\\\\%\text{ error}=15.6\%[/tex]
Hence, the percentage error was, 15.6 %.
