yes. Jennifer and Johny pass their final project.
error = 2.5 %
actual velocity = 34.15 m/s
calculated velocity = 34.87 m/s
so the difference = 34.87 - 34.15
                         Â
= 0.72
2.5 % error allows = 34.15 x 2.5 / 100
                            Â
= 0.85
0.72 is the % error of =( 0.72 / 34.15) x100
                                Â
= 2.1 %
so the teacher mentiond not more than 2.5 % error. this is only
2.1 % error below 2.5% . so they pass their final project.
