Answer 2

Answer:

So, 45 people can plant 2500 plants in 9 hrs

Step-by-step explanation:

35 people can plant 1500 plants in 7 hrs

35 people can plant 1 plant in 7/1500 hrs

=0.0046 hrs

1 person can plant 1 plant in (0.0046×35)hrs

1 person can plant 2500 plants in 0.163×2500 hrs

45 people can plant 2500 plants in 408.33/45 hrs

=9 hrs
