Set Xiao er's horse day trip x Li
The guest's horse travels every hour =300/ 12=25 miles.
Xiao er's horse travels every hour =x/ 12 Li.
When Xiao Er returns to the hotel, there are still 9 hours before the guests leave, which means Xiao Er 9-4=5 hours to go back and forth.
(4+2.5)*25=2.5*(x/ 12)
162.5=2.5x/ 12
2.5x= 1950
x=780
Answer: Xiao Er's horse day tour is 780 Li.
