Let  D  be an unknown distance to Alton.

If Gina drives at  60 km/h,  she will spend    hours,  or   =  minutes to get Alton.

If Gina drives at  90 km/h,  she will spend   hours,  or   =  minutes to get Alton.

According to the condition,  the difference of these times is  40  minutes.  It gives you an equation to determine  D:

- = .

The solution is  D = 120 km.
