Problema Solution

The average length of a human pregnancy is 280 days. However, a healthy, full term pregnancy can be 14 days longer or shorter

Answer provided by our tutors

We will assume that this question wants us to find the range of days that a full term pregnancy usually is.


To get the lower number:

280-14= 266 days


To get the higher number:

280+14=294 days


Therefore the range is from 266 to 294 days.
