Answer:

52.5 days

Step-by-step explanation:

Ten people can dig 2 acres in 7 days.

One person can dig 0.2 acres in 7 days.

Working at half the rate, one person can dig 0.1 acre in 7 days.

8 people can dig 0.8 acres in 7 days.

8 people can dig 6/0.8 * 0.8 acres in 6/0.8 * 7 days.

8 people can dig 6 acres in 52.5 days
