She will exercise for 6 hours in four weeks.
Summer exercises for 0.5 hour on Monday, 0.5 hour on Wednesday, and 0.5 hour on Friday. There are 3 days where she exercises for 0.5 hour.
3 days X 0.5h = 1.5h each week
For four weeks, multiply the hours each week by 4.
1.5h X 4 weeks = 6h
Therefore Summer will exercise for 6 hours over the course of 4 weeks.
