S TATION 1 I went picking blueberries with my grandmother, and she always went to the rows you weren’t supposed to pick, so we had to go fast. I could pick a row in 20 min, but she could do it in 12. How long would it take for us to do it together?
S TATION 2 I can eat the delicious blueberry by all by myself in 3 hours. My friend Eric and I can eat one together in 1 hour and 40 min. How long would it take for Eric to eat it by himself?
S TATION 3 Turns out my blueberry pies were so delicious that I opened up a blueberry pie store. My first worker could make enough pies to fill my orders in 12 hours, so I hired a second worker who could do the whole job in 8 hours. They worked for 2 hours, and I saw they weren’t going to finish. I worked with them for 90 min and we finished. How long would it take me to do the whole job by myself?
