Step-by-step explanation:
add the money then add the other numbers
The answer is A, with a change of 41. B has a change of 32. C has a change of 35. D has a change of 29.
I am not sure, but I'll give you the layout.
Step-by-step explanation:
32/160= p/100
P=?
P stands for the percent
Based on the calculations, the slowest rate is equal to 4 gallons per minute.
<u>Given the following data:</u>
- Distance from shore = 12 km.
- In-rate = 3 gallons per minute.
- Rowing rate = 24 km per hour.
<h3>How to calculate the slowest rate.</h3>
Let's assume the boat would sink if it takes in more than 20 gallons of water.
<u>Conversion:</u>
- 24 km/h to km/min =
= 0.4 km/min.
Translating the word problem into an algebraic expression, we have;
Therefore, the slowest rate is equal to 4 gallons per minute.
