 
 <prompt> Stephen waka go up and down di 40,000 foot tall mountain 10 times. If e reach 3/4 of di mountain height for each trip, calculate di total distance wey e cover. <response>: ```Up a mountain, Stephen cover 3/4*40000 = 30000 feet.
Coming down, Stephen cover another 30000 feet, making the total distance wey he cover for one round to be 30000+30000 = 60000.
Since Stephen do 10 round trips up and down the mountain, he cover 10*60000 = 600000

The final answer: 600000.```
