your answer is 53 1/4.

There are 7 days in a week. multiply 15 1/4 by 7. you should get 106 3/4. subtract that from 160, and you should be left with 53 1/4. I hope this helped :))

While evan and sam are fishing 12kms from shore, their boat springs a leak, and water comes in at a constant rate of 3 gallons p

aev [14]

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 = $\frac{24 }{60}$ = 0.4 km/min.

Translating the word problem into an algebraic expression, we have;

$\frac{12}{0.4} \times 3 - \frac{12}{0.4} \times x\geq 30\\\\\frac{36}{0.4}-\frac{12x}{0.4} \geq 30\\\\90-\frac{12x}{0.4} \geq 30\\\\\frac{12x}{0.4} \geq90+30\\\\\frac{12x}{0.4} \geq120\\\\12x \geq120 \times 0.4\\\\12x \geq 48\\\\x\geq 4$
