Accounting for Van#2's night shift

Eric ran twice and everyone else ran fast. Damp weather and the dark made
for good running. Distances and tiimes:

1. Eric - 6.3 miles. 51 minutes and 15 seconds
2. Steve - 7.6 1:00:50*
3. Marc - 6.5. 46:41
4. Brad - 3.0. 25:23
5. Eric - 6.9. 57:48
6. Fred - 4.0 29:28*

For the shift in total, that's 34.3 miles in 4 hours and 31 minutes.

*their fancy watches may tell a slightly different story. Believe them.
