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.

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.
