(100*7 + 300*2 + 200*6)/15 = 166.67
It always helps if you show your own work - then it's possible to point out the mistake, if any.
Jill burns 100 calories per hour while sleep and 300 calories per hour while walking and 200 calories per hour at work. If in a typical day Jill spends 7 hours sleeping, 2 hours walking and 6 hours working, what is her average calories burned for those hours?
166.67 cal/hr
200 cal/hr
133.3 cal/hr
233.67 cal/hr
I got 140 cal/hr... how do I do this problem?
