Take this for what ever its worth: Explain your situation in a positive, non-confrontational way. Tell your sup what you told us. By working only one hour, with the cost of gas, you will have lost money coming in. Then offer a compromise: Tell them you understand they may be overstaffed on some days and have no work for you with you being at the bottom of the totem pole, but if they would then let you know ahead of time and call you on days they will not be needing you.
In addition, depending on how quickly you make friends and all, if you are so far away from work, can you car pool with someone at least part of the way? (The person would have to live in the same basic direction.)
