Question

anonymous · Answer

Well if you swim for 30 minutes, how much time is spent biking?

You have the rates for each activity...so use those to calculate each activities' burned calories then add them up.

swim_cal = swim_time * 15
bike_cal = bike_time * 5
swim_time + bike_time = 60

30 minutes swimming:  30(15)=450 calories burned while swimming
30 minutes biking:        30(5)=150 calories burned while biking
Total calories burned = calories burned swimming + calories burned biking
