While exercising, carly burns 450 calories per hour biking and 620 calories per hour playing racquetball. sarah burns 560 calories per hour running and 510 calories per hour playing squash. in a workout consisting of 30 minutes of each respective exercise, who burns more calories?

It will be both of the girls burn the same amount of calories because 450/2 will give you 225 then you divide 620/2 you'll get 310. If you add 225+310, it will give you 535. That is for Carly. Then if you do 560/2, it will give you 280 then you divide 510 by 2, you'll get 235. 280+235= 535. That is for Sarah. As you can see, they are both the same results. I hope this is right!
