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

### Instruction:
Max can mow the lawn in 40 minutes. If it takes him twice that long to fertilize the lawn, how long will it take him to both mow and fertilize the lawn?

### Response:
Fertilizing the lawn takes 2 * 40 minutes = <<2*40=80>>80 minutes.
In total, Max takes 80 minutes + 40 minutes = <<80+40=120>>120 minutes to both mow and fertilize the lawn.
