X = 72 and it's a scalene triangle
If x is the amount of time Gillian takes,
1/10 - 1/x = 1/25
Therefore, the answer is A
For this case we have the following fractions:

We must rewrite the fractions, using the same denominator.
We have then:
We multiply the first fraction by 11 in the numerator and denominator:

We multiply the second fraction by 2 in the numerator and denominator:

Rewriting we have:
For the first fraction:

For the second fraction:

We note that:

Answer:
The fractions are not equivalent:
