Answer: 3 min
Step-by-step explanation:
Step 1. Find the constant speed
you walked 1000 feet in 15 min
1000 ft/ 15min=200/3 ft / min
Step 2. Apply the constant speed to the left distance
You already walked 1000 feet and it is total 1200 feet
1200-1000=200 feet left
distance ÷ speed=time
200 ÷ (200/3)=3 min
Hope this helps!! :)

The question is "What's Stella's opportunity cost of working on her serve for an hour?" The rest of the info looks like it's meant to confuse you. They charge $10 an hour. She values an hour of her time at $20. I believe that means she would pay $20. Hope this helps!
