One week, Mrs. Peterson went to her health club on Monday, Wednesday, and Friday. Each day she went to the club, she jogged on the treadmill for 3/5 hour, lifted weights for 1/4 hour, and then cooled down by stretching for 1/4 hour. On Saturday, she rode her bike for 3/4 hour. How many hours did she spend riding and bike and exercising at the health club that week?
Answer choices:
3 1/20 hr, 29 3/5 hr, 4 1/20 hr, and 5 11/20 hr. Please help!
