A similar triangle means it is of a diferent size, but the sides or angles are proportionaly the same.
Use the rule of 3 on each number, to find the equivalent sides:
65 - 39
60 - x
(60 * 39) / 65
2340 / 65
36cm
60 - 36
25 - x
(25*36) / 60
900 / 60
15cm
Original triangle: 65, 60, 25
Similar triangle: 39, 36, 15

Answer is 800/p
800 is the number of planks divided by how many she paints a day to calculate the number of days.
Let's translate the verbal language to algebraic language.
She rides to and from school 5 days per week, 6.25 miles each route => 5*2*6.25 miles = 62.5 miles.
She rides additioanly around the park 2.5 miles for each trip t => 2.5*t = 2.5t
Total miles of her rides per week: 62.5 miles + 2.5t
She wants to ride minimum 85 miles => 62.5 + 2.5t ≥ 85
Then, the situation is represented by this inequality:
2.5t + 62.5 ≥ 85
You can develop it and get to several equivalent inequalities, for example:
2.5t ≥ 85 - 62.5
2.5t ≥ 22.5
t ≥ 9
Any of the four forms are equivalent and a valid answer.
