Hint
How old was the person in 2^nd place?

Answer
# Name    Age
1 Drew    30
2 Emery   24
3 Glen    27
4 Alex    32

Reasoning
By (2), because Glen was three years older, the person in 2^nd place was either 24 or 27.

But 2^nd place can't have been 27, because, by (4), Emery was ahead, but didn't win.

So 2^nd place was 24, and Glen was 27.

By (3), Drew could only be 27 or 30, but we now know what Glen was 27, so Drew was 30.

By (1), the person who came last was 32:
1
2         24
3
4         32

By (4), the 27 year old can't have won,
1 Drew    30
2         24
3 Glen    27
4         32

By (4), Emery beat the 27 year old:
1 Drew    30
2 Emery   24
3 Glen    27
4         32

Leaving Alex in last place.
1 Drew    30
2 Emery   24
3 Glen    27
4 Alex    32

Hint
How many days separate the two dates?

Answer
18 days.

Reasoning
There are 140 days between the two dates, and these 140 days are split in the following way:

   4 x Answer | 50 days | Answer

We already know about 50 days, so we have to split the remaining 90 days into the ratio 4:1, which is 72:18.

   72 days | 50 days | 18 days
