**Answer:**

9.08 hours

**Step-by-step explanation:**

in order to fill 1 pool

fill rate by pipe = 1 pool / 15 hours = 1/15 pool per hour

fill rate by hose = 1 pool / 23 hours = 1/23 pool per hour

combined rate = fill rate by pipe + fill rate by pool

= 1/15 + 1/23 = 38/345 pool per hour

since:

38/345 pool -----------> will take 1 hour

1 pool --------------------> will take 1 hour x (345/38) = 9.08 hours

64/4 = $ 16 per video game

**Answer:**

Jada and lin are comparing inches and feet.

Let I denote inches and F denote feet.

It is given that

I =k F or F=m I

So, I/F=k or m=F/I

As we know 1 feet = 12 inches

constant of proportionality i.e k=1/12

In case 2, constant of proportionality=12/1=12

So, Jada must have calculated ratio of feet to inches while Lin has calculated the ratio of inches to feet.
