On the planet Orbius-5, there are 250 days per year, and each year is equally divided into 5 seasons. If an astronaut from earth lands on planet Orbius-5 and stays there for 3 seasons before returning to earth, what is the number of days the astronaut will spend on Orbius-5?
If 1 year is 250 days, and each year is divided into 5 equal-length seasons, then each season is 250/5=<<250/5=50>>50 days long.
If an astronaut stays on the planet for three seasons, then they remain there for 3*50=<<3*50=150>>150 days.
