Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
Emma can run all-around two arenas in 20 hours. If it takes Fernando twice as long to run his course, what's the total time it takes both of them to run all around the two arenas?

### Response:
If it takes Emma 20 hours to run all around the two arenas, it takes Fernando 2*20 = <<20*2=40>>40 hours to run the same distance.
The total time it takes both of them to run all around the arenas is 40+20 = <<40+20=60>>60 hours
