There are 60 workers in a furniture factory, processing a table with a desktop and four legs. Workers can process three desktops or six legs every day. How to allocate the number of people processing desktops and legs so that the desktops and legs produced every day match?

Set up a worker to handle the desktop, and then you have 60-a workers to handle the legs.

3a = (60A) ×6/4

12a=360-6a

18a=360

a=20

20 people process the desktop, 60-20=40 people process the legs.

2. When the plane flies between two cities, the wind speed is 24km per hour, and it takes 17/6 hours to fly with the wind and 3 hours to fly against the wind, so find the distance between the two cities.

Suppose the distance is one thousand meters.

a/( 17/6)-24=a/3+24

6a/ 17-a/3=48

A=2448 km
