During her 8th week of training a woman ran 20 total miles,during her 13th week of training she ran 33 total miles.
If the woman ran 37 miles,what week of training would she be in
so 8th week:20 13th week:33 13-8=5 33-20=13 grouth of 13 per 5 weeks or about 2.6 increse per week
so if she ran 37 miles then 37-33=4 so an increse of 4 or about 1.5 more weeks soweek 14.5
another way is to find the ratio of miles to weeks 20/8=2.5 33/13=2.54 average 2.5 and 2.54 and get 2.52 37/x=2.52 solve for x 37/x=2.52 multiply both sides by x 37=2.52x divide both sides by 2.52 14.68=x she is on her 14.68 week you might want to round up
