So for this lawn care service, we have one worker mows 6 ,000 meters squared per hour.
00:14
And in part one, we want to know how much area in one hour with many workers.
00:35
So let's imagine that we have our first worker and he mows the 6 ,000 meters squared.
00:42
He can do in an hour.
00:43
The second worker works alongside and does another 6 ,000 meters.
00:49
So the amount, the total here is two.
00:53
Times 6 ,000 meters squared.
01:01
We add a third worker with the same productivity.
01:07
And then here the total is now 3 times 6 ,000.
01:14
So we see that the total area, we'll call area as a and workers as w.
01:26
So the total area is equal to the number of workers times 6 ,000.
01:34
So we see that it's linear.
01:36
Every worker adds their extra area to mow...
