In Enos
1:25 etc. Longevity of Nephite Scribes the late John A. Tvedtnes addressed
the following criticism:
In the Book of Mormon, Enos wrote that 179
years had passed away from the time that his grandfather, Lehi, left Jerusalem
(Enos 1:25). Later, Enos’s son Jarom says 238 years had passed away (Jarom
1:13). It is unreasonable to expect that three generations (Lehi’s son Jacob,
his son Enos, and his son Jarom) could have lived so long.
Interestingly,
there are modern examples of such. In the following video from 2014, two
children (at the time of recording, ages 92 and 93) of participants in the US Civil War (1861-1865) talk about their
fathers, showing that such longevity of some Book of Mormon peoples is not
unusual:

Another interesting video is how US President John Tyler (born 1790; died 1862) still has two living grandsons:

Update: My friend Bruce Webster shared with me something he wrote back in 2009 on this issue:
