Question

Cory predicts it will take him 64 minutes to travel to Baltimore from Washington D.C. If the trip actually took 74 minutes, what was Cory's percent error? Round your answer to the nearest tenth of a percent.

Answer 1

The percent error is 80%

Answer 2

Answer : The percentage error was, 15.6 %.

Step-by-step explanation :

To calculate the percentage error, we use the equation:

`\%\text{ error}=\frac{|\text{Experimental value - Accepted value}|}{\text{Accepted value}}* 100`

We are given:

Experimental value = 74 minutes

Accepted value = 64 minutes

Putting values in above equation, we get:

`\%\text{ error}=(|74-64|)/(64)* 100\\\\\%\text{ error}=15.6\%`

Hence, the percentage error was, 15.6 %.
