You estimate the distance from your house to the library to be 2.4 miles. the actual distance is 2.6 miles. find the percent error. round your answer to the nearest tenth of a percent.

7.7%

Step-by-step explanation:

To find the percent error, take the absolute value of (actual amount - estimate) and divide it by the actual amount).  Then multiply it by 100 %

percent error = | actual - estimate|

                          * 100%

                             actual          

                      = | 2.6 -2.4|

                        * 100%

                                  2.6

                      = .2 * 100%

                            2.6

                       =7.69230769%

To the nearest tenth percent

                      =7.7%
