First day:

the displacement is 10 km west

so we have

$d_1 = -10 \hat i$

Second day

10 km west again

so we have

$d_2 = -10 \hat i$

Third day:

10 km west again

so we have

$d_3 = -10 \hat i$

Fourth Day:

20 km East as they return to the Inn

so we have

$d_4 = 20 \hat i$

so total displacement of Ben and Jerry till fourth day from home is given as

d = d_1 + d_2 + d_3 + d_4

$d = -10\hat i - 10\hat i -10\hat i + 20 \hat i$

$d = -10\hat i$

so final displacement from home is 10 km west
