Answer #1

Please don't hesitate to give a "thumbs up" in case you're satisfied with the answer

the expected time of departure from home is midway between 8 to 8.30 am because the relation is linear.

So, 8,15 is the time he is expected to start for work

It takes 30 to 40 minutes to reach, so expected time to reach is (30+40)/2 = 35 mins

So, 35 minutes on top of 8.15 am is 8.50 am

d) is correct
