Here we can draw the diagram as below from the facts given in the statement.

Let the distance between Jonna's house and Russel's house = X

SO the distance between Russel's house and diner = X - 2

By using Pythagoras theorem we have,

$$X^2 = (X - 2)^2 + 10^2$$

or $$4X = 104$$

or $$X = 26$$.

Therefore the distance between Russel's house and diner = $$X - 2 = 26 - 2 = 24$$

"Russell's house is 2 miles closer to the diner than to Jonna's house" - Doesn't it mean 10-2=8 ? Please explain.

Here dinner is a 'place', so Russel's house is 2 miles closer to dinner than Jonna's house (also a place). So it means that if distance between Jonna's and Russels place is $$x$$ then the distance between dinner and Russels place is $$x-2$$.

I had the same issue as the other poster until I realized my reading was skipping TO, which I highlighted in the quote. What the poster (and I initially) read was

"Russell's house is 2 miles closer to the diner than Jonna's house"

"Russell's house is 2 miles closer to the diner than to Jonna's house"
