hello I am making a speedometer for skiing using a neo-7 gps module and a .96 inch oled. I was wondering if I could power it by 6 aa batteries.
Indeed, very possible. Or perhaps 4 AA batteries if you only need 5V.
Careful with powering the gps - some are 3.3v supply , all need 3.3v on the serial coms.
For skiing, why not make a talking GPS speedometer?
That way you don't have to look at a tiny display, while running into a tree at 90 km/h.

You just need to use 4 AA batteries as it becomes 6V and can power up the GPS module from 5V & GND of Arduino. neo-7 gps module works on 5V.

Might work, but only if you always go in a straight line. Any difference between GPS readings is a straight line from one to the other.

The Neo-7 is a GPS module that is designed to run on 3.3V. Do not connect 5V to the module it will be destroyed.
What you are refering to as a 'module' might well be a GPS breakout board that has the Neo-7 module on it and other components such as a regulator or logic level conversion.
