Step-by-step explanation:

1) What is the amount of pie Joe can eat in 1 hour? of a pie per hour

Use a proportion :

1/4 - 180 mins

?    - 60 mins                           Solve: 60 * 1/4 = 15, 15/180= 0.083 or 83/100.

Joe can eat 0.083 or 83/100 of a pie in 1 hour.

2) How long does it take Joe to eat 1 pie?hours

Use a proportion :

1/4 - 180 mins

1    - ?

1/4=0.25

Solve:  180*1=180, 180/0.25=720

720mins/60mins =12

It takes Joe 720 mins or 12 hours to eat 1 pie

the discriminant is 64 + 4*1*12 = 112
