cindy exercise for 30 minutes 2 times a day . if she keeps up this schedule for 30 days, how many minutes will she exercise in all
So 30 minutes twice a day means you would do 30x2=60. 60 minutes is an hour so if she is exercising for an hour a day for 30 days she is exercising 30 hours. 60 minutes in an hour so (1,800 minutes) is your answer.
