Cordell Barry · Answer 1

40 min - total time of workout.

20 min - of running workout

40-20=20 min of swimming workout

r=20

20*20+r10=40

We know that r equals to 20 now

20*20+20*10=40

400+200=600

Answer: 600 calories were burns while doing a 20 minute swimming workout and 20 minute running workout.

Darcy · Answer 2

If you're running for 20 minutes, that means you swim for 20 minutes (40-20=20).

Calculate the calories you will burn by running.

20*20 = 400.

Then calculate the calories you will burn swimming.

20*10=200.

Then add them together.

400+200 = 600.

The answer is 600 calories.
