Neee asa is training for a race that is 10 kilometers long. on saturday he ran 2.5 km. he plans to add 0.5 km to his distance every saturday. hector's calculations: 2.5 + 0.5 = 3.0 6.5 + 0.5 = 7.0 3.0 + 0.5 = 3.5 7.0 + 0.5 = 7.5 3.5 + 0.5 = 4.0 7.5 + 0.5 = 8.0 4.0 + 0.5 = 4.5 8.0 + 0.5 = 8.5 4.5 + 0.5 = 5.0 8.5 + 0.5 = 9.0 5.0 + 0.5 = 6.0 9.0 + 0.5 = 9.5 6.0 + 0.5 = 6.5 9.5 + 0.5 = 10.0 the equation equivalent to hector’s calculations is 2.5 + 0.5x = 10. use either of these methods to determine how many weeks it will take hector to reach his goal of a 10 kilometer run.
