So this is a school project, and you want to observe the movement of a RPI which has a GPS device. Data volume is low.
And it is low budget.
My proposal would be to plan for a three step implementation.
In first step you assume that there is WIFI coverage for both Pi. Design the software to clearly separate the communication backend from the GPS acquisition on one Pi or the data receive and display part on second Pi. With this step completed, you demonstrate basic working principle and that you master the complexity.
In second step use small communication module like HC-12 modules or RFM69. Depending on legal rules in your country which define RF power settings, you have 50 to 100m range, some more in free sight. As the communication backend is separated from the other parts of software, this exchange should be simple. With this step you demonstrate the flexibility of the system.
A third step could be to use high power radio, or cellular net, or LORA, or satellite or whatever is considered long range. You will most probably not implement this due to budget constraints, but could draw it on your presentations to demonstrate "constructive foresight".
