To solve this problem, you can create a system of equations and solve for each hiker's distance walked.
Hiker 1 distance walked: x
Hiker 2 distance walked: y
Their combined distance walked is 53 miles, thus -
x + y = 53
The difference between miles walked is 25, thus -
x - 25 = y
Let's solve using substitution. To do that, substitute x - 23 into x + y = 53 for y.
x + y = 53
x + (x - 25) = 53
x + x - 25 = 53
2x - 25 = 53
2x = 78
x = 39
To find y, substitute 39 for x into either of the equations.
x + y = 53
39 + y = 53
y = 14
Finally, check all work.
x + y = 53
39 + 14 = 53
53 = 53
x - 25 = y
39 - 25 = 14
14 = 14
Answer:
One hiker walked 39 miles and the other hiker walked 14 miles.
If a number is rational it means, it can be written in the form of 
, where q≠0 and p and q can be any integers.
There are following properties possessed by Rational numbers
1. Decimal representation of Rational numbers are either terminating or non terminating repeating i.e if the denominator is of the form 
where m and n are any natural number.
2. Addition ,Subtraction ,Multiplication and Division of two rationals is always Rational.
3. The sum or difference of rational and irrational is always irrational.
