Answer: 3 miles per hour
<u>Step-by-step explanation:</u>
Use the formula "distance (d) = rate (r) x time (t)" to create a system of equations.
Let "r" represent the rate they are rowing
Let "c" represent the current
time rate distance <u>EQUATION</u>
Downstream: 4 hours r + c 40 miles 4(r + c) = 40
Upstream: 10 hours r - c 40 miles 10(r - c) = 40
Distribute, then eliminate r to solve for c:
Down: 4r + 4c = 40 → 5(4r + 4c = 40) → 20r + 20c = 200
Up: 10r - 10c = 40 → -2(10r - 10c = 40) → <u>-20r + 20c</u> =<u> -80</u>
40c = 120
<u> ÷40 </u> <u>÷40 </u>
c = 3
− 10/8
− 15/12
− 20/16
− 25/20
− 40/32
These are all equal, the list could go on but here are many
Answer:
4 plants
Step-by-step explanation:
In this problem, we are given the total area of the garden, which is:
The number of plants that can fit inside the garden is given by the equation:
where:
n is the number of plants
a is the area of each plants
In this problem, the area of each plant is
Therefore, we can re-arrange the equation to find the number of plants that can fit:
