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

### Instruction:
 Stephen made 10 round trips up and down a 40,000 foot tall mountain. If he reached 3/4 of the mountain's height on each of his trips, calculate the total distance he covered.


### Response:
 Bei jeder Reise hat Stephen (3/4) * 40.000 = 30.000 Fuß zurückgelegt.
Er hat 10 Reisen gemacht, also beträgt die Gesamtstrecke, die er zurückgelegt hat, 10 * 30.000 = 300.000 Fuß.
