Question

A landowner in Missouri employed 10 laborers to plant a total of 10,000 seedlings. If each laborer planted one seedling every 15 seconds, in how many minutes were all 10,000 seedlings planted?

Answer 1

Number of seedlings planted in 15 seconds

= 10 laborers x (1 seedling/15 seconds per laborer)

= 10 seedlings/ 15 seconds

 

Each 15 seconds is 1/4 minute say 0.25 minutes

 

Number of seedlings /minute =

(10 seedlings/0.25minutes) = 40 seedlings /minute

 

Number of minutes = (1000 seedlings) / ( 40 seedlings /minute)

= 250 minutes
