    I would use ratios 2 inches is to 25 miles as x inches is to 60 miles we would write that like this \[ \frac{2}{25}= \frac{x}{60} \] to "find x" , I would multiply both sides by 60, like this \[ \frac{2}{25}\cdot 60= \frac{x}{60}\cdot 60 \] can you finish ?

    \[\frac{ 120 }{ 1500 }\] and \[\frac{ X }{120 }\]

    you should get \[ \frac{2\cdot 60}{25} = x \]

    I am not sure what you did but it is worth getting the idea (if you have time) \[ \frac{2}{25}= \frac{x}{60} \] if you multiply both sides by 60, this make the 60 on the right side "go away" because \[ \frac{x\cdot 60}{60} = \frac{x\cdot \cancel{60}}{\cancel{60}} =x\]

    and on the left side \[ \frac{2\cdot 60}{25} = \frac{120}{25} \] so \[ x= \frac{120}{25} \] you can simplify that. what do you get ?
