Answer 1

Given the rates:

• 16 carrots for $4

,

• $36 for 3 hours

,

• 420 miles in 6 hours

Let's write the given rates as unit rates.

To find the unit rate, divide each unit by the number on the right side,

Hence, we hae the following:

• 16 carrots for $4

`\text{Unit rate = }\frac{16\text{ carrots}}{\text{\$4}}=(4)/(1)=4\frac{carrots}{\text{ \$}}=4\text{ carrots per dollar}`

• $36 for 3 hours:

`\text{Unit rate = }\frac{\text{ \$36}}{3\text{ hours}}=12\frac{\text{ \$}}{\text{hour}}=12\text{ dollars/hour}`

• 420 miles in 6 hours:

`\text{Unit rate=}\frac{420\text{ miles}}{6\text{ hours}}=70\frac{miles}{\text{hour}}=70\text{ miles/hour}`

Therefore, the rates written as unit rates are:

• 16 carrots for $4 ==,> ,4 carrots per dollar

,

• $36 for 3 hours, ,==>, ,12 dollars per hour

,

• 420 miles in 6 hours, ,==> ,70 miles per hour

ANSWER:
