like who does that Which inequality represents how many meters

00:20

x jill needs to swim to reach that goal Phrases

00:28

like more than and twice as many sound like everyday

00:32

phrases but both are encoded tightly with mathematical clues just

00:36

waiting to be cracked very specifics You gotta be exact

00:39

when you describe them start with a phrase twice a

00:41

cz many well for every meter jill swims katie swims

00:45

too We don't know how many meters jail was able

00:47

tio doggy paddle though so that value is x The

00:50

number of meters katie swims is two x will combine

00:54

the girls swim x plus two Acts or 3 acts

00:57

meters If you get that everything is a smooth sailing

01:01

or swimming or whatever Whatever value three ex winds up

01:04

being it must be mohr than three sixty if the

01:07

girls want to meet their goal well the problem doesn't

01:09

say anything about three sixty being adequate so use the

01:12

greater than symbol not the greater than or equal to

01:15

symbol Yeah so that that d there would be wrong

01:18

it's gotta be c three Acts is simply greater than

01:21

3 sixty not equal to it and that's the accurate

01:24

representation of the number of meters jail needs to cover 00:01:28.064 --> [endTime] that's it we're done
