Answer: 103/15
Step-by-step explanation:
We can simplify the right-hand side to be
.
This means we need to solve:

It takes 6 minutes to circulate 2.5 gallons of water
we are given
6 × 8 = 48
we know that
commutative property of multiplication:

now, we will verify each options
option-A:
we have
6 × 8 = 48
now, we can find it's commutative
so, we get
8 × 6 = 48
so, this is TRUE
option-B:
we have
6 × 8 = 48
now, we can find it's commutative
so, we get
8 × 6 = 48
so, this is FALSE
option-C:
we have
6 × 8 = 48
now, we can find it's commutative
so, we get
8 × 6 = 48
so, this is FALSE
