Kona Rove Steel: Limited Gearing for Hills?

I rode a Kona Rove Steel and liked it, but the gearing seems rather limited for climbing hills. I believe it has a 40 tooth chainring and an 11-42 cassette. (I think this yields something like 26.8 gear inches for inclines. Check me on this as I'm not real clear on all of these calculations!) Is this acceptable for hills for the aging "recreational" rider? Thanks.
