Luke: 2 miles in 40 minutes, 20 minutes a mile, (2/40 = 20 minutes a mile)
Luke's speed is 3 miles an hour (60minutes/20minutes a mile = 3miles).

Sally: 0.05 miles a minute, 60 minutes in an hour, 60 x 0.05 = 3 miles an hour.  Or 0.05 miles a minute, 40 minutes walked, 40 x 0.05 = 2 miles walked.

There are a few other ways to show that they are accurate rates. 

So yes, they are both correct rates.

Step-by-step explanation:

(68/17)*1=4

3. We first see how many 3ins are in 9ins, and than multiple that with 9feet

(9/3)*9=3*9=27

4. First see how many 2ins are in 36ins, and then multiple it with 7.

(36/2)*7=18*7=126feet

5. See how many 15fts are in 75ft And than multiple it with 3.

What is the value of x in the equation 2(x – 3) + 9 = 3(x + 1) + x?<br>x = <br>​
sukhopar [10]

Start with

2(x-3)+9=3(x+1)+x

Expand both parentheses by multiplying both terms by the number outside:

2x-6+9 = 3x+3+x

Sum like terms:

2x+3 = 4x+3

Simplify the "+3" on both sides:

2x = 4x

Subtract 2x from both sides:

2x=0

Divide both sides by 2:

x=0
