Conversion:
1 week=7 days
1 day=24 hours

Convert:
268 hours(\frac{1 day}{24 hours})=11.17 days
11.17 days(\frac{1 week}{7 days})=1.6 weeks

They worked for 1.6 weeks or 11.17 days, or 268 hours, or simply(in mixture)1 week 4 days and 4 hours. Hope this helps =)

We have the following conversions:
1 week= 7 days
1 day= 24 hours

So we convert 268 hours to days and we get:
 \frac{268}{24} =11r4
So we have 11 days and 4 hours.

We convert 11 days to weeks:
 \frac{11}{7} =1r4

Therefore he worked 1 week 4 days and 4 hours
