X = No. of professors
x + 14x = 37,500
(No. of professors + 14 times the no. of professors = total)
Add.
15x = 37,500
Isolate x by eliminating 15.
15x/15 = 37,500/15
x = 2,500
There are 2,500 professors in the college.
37,500 - 2,500
(Total - no. of professors = no. of students)
= 35,000
There are 35,000 students in the college.
♧
190x + 210x = 2000
400x = 2000 <-- Combine like terms
x = 5
In 5 hours they will separated by 2000 miles.
