Question

Ten people can dig 2 acres of land in 7 days. How long will 8 people working at half the rate of the first group take to dig 6 acres of piece of land?​

Answer 1

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
