You ran 3 1/2 mi in 3/4 hr your friend ran 1 2/5 mi in 1/3hr which of you ran faster

Answers

Answer 1

Answer: "You" ran faster. 3 1/2 mi. turn into 3 5/10 mile. 1 2/5 mi. turn into 1 4/10 mile. 3/4 of an hour is 45 min. 1/3 of an hour is 20 min. Therefore you multiply 1 4/10 times 2 to get 2 8/10 mi. in 40 min. Since your friend needs 5 more min. to be at the same time as you, you divide 20 (1/3 of an hour) by 4. Which gives you 5 minutes. Now, take the 1 2/5 of the mile. and divide that by 4. Which according to Symbolab.com gives you 1/10. Now go back to the beginning, you ran 3 5/10 mi. in 45 minutes. Your friend ran 2 8/10 in 40 min. Now that we know 5 min. equals 1/10 miles, you can add that to your friend. which means she/he ran 2 9/10 mi. in 45 min. In conclusion, you ran farther that your friend in 45 min. "You" ran faster. (:

Answer 2

Answer:

Final answer:

To determine who ran faster, divide the distance traveled by the time taken for each person and compare their speeds. Your speed is greater than your friend's speed, so you ran faster.

Explanation:

To determine who ran faster, we need to compare their speeds. Speed is calculated by dividing the distance traveled by the time taken. Let's calculate their speeds and compare them:

Your speed = Distance / Time = 3 ½ mi / ¾ hr = 4.67 mi/hr
Your friend's speed = Distance / Time = 1 ²/5 mi / ⅓ hr = 3.42 mi/hr

Since your speed is greater than your friend's speed, you ran faster than your friend.

What is the decimal representation of 5/11

Answers

Answer:

$(5)/(11)=0.\overline{45}$

Step-by-step explanation:

Given: $(5)/(11)$

We need to change given fraction into decimal.

$x=(5)/(11)-------(1)$

$11x=5$

Multiply both sides by 9

$99x=45-----------(2)$

Add equation (1) and (2)

$99x+x=45+(5)/(11)$

$100x=45.45.....$

Divide both sides by 100

$x=0.454545.....$

$(5)/(11)=0.454545.......=0.\overline{45}$

0.45 is the answer but
0.45454545454is it

How do you find the constant of proportionality

Answers

to find the constant of proportionality here let's look at the equation of a line for a straight graph that passes through the origin. y is your vertical y-value for any given point on the line, x is your horizontal x-value for any given point on the line, and m is the slope.

Answer:

The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.

Step-by-step explanation:

Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.

What is the answer? 6.3 = 0.7x

Answers

Answer:

x = 9

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Divide 0.7 from both sides:

6.3 = 0.7x

(6.3)/0.7 = (0.7x)/0.7

x = 6.3/0.7

x = 9

x = 9 is your answer.

Answer:

Step-by-step explanation:

6.3/.7=x
