A family is canoeing downstream (with the current). Their speed relative to the banks of the river averages $2.75 mi / h$. During the return trip, they paddle upstream (against the current), averaging $1.5 mi / h$ relative to the riverbank. Write and solve a system of equations to find the family's paddling speed in still water. Let s equal the families paddling speed and c represent the current.
A. $s + c =2.75$
$s-c=1.5$
B. $2.75 s= c$
$1.5 s=c$
C. $s + c =2.75$
$c-s=1.5$
D. $2.75 c=s$
$1.5 c=s$
Answer (3)
18 pots because 4 times 18 equals 72
18 pots because 72 divided by 4 is 18 and that is a summary model I believe
Joe needs 18 pots to hold all 72 plants, as each pot can hold 4 plants. This is calculated by dividing 72 by 4. Therefore, 72 ÷ 4 equals 18 pots needed.
