Alana and kelsa are training for a marathon. to prepare for this marathon they have been training and tracking their progress periodically.
in the first week of training alana ran an average of 14 minutes per mile. later, in week nine of training she ran an average of 10 minutes per mile.
in the first week of training kelsa ran an average of 11 minutes per mile. later, in week eight of training she ran an average of 9 minutes per mile.
assuming alana and kelsa continue to train and improve their times at the same rate your task it to determine which week they will have the same average minutes per mile. we will assume that the relationship is linear as they will be training for a maximum of 43 weeks. to complete this task follow the steps below.
1. determine the equation of a line in standard form that represents alana's training progress. her progress corresponds to the points (1,14) and (9,10).
2. determine the equation of a line in standard form that represents kelsa's training progress. her progress corresponds to the points (1,11) and (8,9).
3. solve the system of equations (show all work)
4. in which week will alana and kelsa have the same average minute per mile?
5. if alana and kelsa continue to train until week 30, what will their times be?
