Question

16. The number of hours needed to clear the trees
from some land is inversely proportional to the
number of people who are working. If it would
take 4 people 15 hours to do the job, how many
people would be needed to complete the job in
6 hours?​

Answer 1

Step-by-step explanation:

Number of people need to clear the tree in 15 hours = 4

Number of people need to clear the tree in 1 hour = 4 × 15

Number of people need to clear the tree in 6 hour =

4*15/6

= 10

Hence, the number of people need to clear the tree in 6 hours is 10 people.
