It seems like it's taking quite a while for you to figure this out.
この場合、次のように言うと良いでしょう。
ーDoes it take this long for you to look into it?
「調べるのにこんなに長くかかるの?」
to look into で「…を調べる」
ーIt seems like it's taking quite a while for you to figure this out.
「これを解決するのに随分長くかかっているようですね」
to figure out で「解決する」
このような言い方もできるかと思います。
ご参考まで!
"調べるのにそんなに時間がかかるの?"
- It takes that much time to look it up?
- It takes that long in order to look it up?
- Why is it taking so long?
