First we need to convert yard to miles
3520yards÷1760yards/mile=2 miles
From there we know:
Alex walked 1 mile for 15 mins and Sally walked 2mile in 24 mins
We need to convert these mileages to miles per hour
1mile/15mins*60mins/hour=4miles /hour
2mile/24mins*60mins/hour=5miles per hour
Alex walks at 4 miles per hour and Sally at 5 miles per hour
Sally walks 1 mile per hour faster than Alex

Answer:
0
Step-by-step explanation:
3 <em><u>-</u></em> (<u><em>-</em></u>1) + (-1) -3 =
Minus and a negative makes it positive. In other words it would be written like this: 3 + 1 <u><em>+</em></u> (<u><em>-</em></u>1) - 3 =
Next step would be making it minus 1, because plus sign and negative makes the number to be subtracted. It would be rewritten like this: <em><u>3 + 1 </u></em>- 1 - 3 =
Then you will simply add 3 and 1, which makes it 4. So it would be rewritten likes this: <em><u>4 - 1</u></em> - 3 =
Then you will simply subtract 1 from 4, which would equal to 3. So it would be rewritten like this: <em><u>3 - 3</u></em> =
Last step, would be subtracting 3 from 3. Whatever is subtracted from itself would always be 0.
So the answer would be 0!
This is not my answer I found it from another brainly
From the beginning we know we are dealing with two different rates. Distance is equal to (Speed X Time). We have two different speeds though. We will call the min speed = x and the max speed = y. With those two ideas in place we can make two equations for both Tony and Rae.
Tony:
2x+3.5y=355
Rae:
2x+3y=320
Now you can solve the equations by subtracting Rae's equation from Tony's
.5y=35 solve for y and you get 70
Now plug that y value back into either equation and you can solve for x. I'll use Rae's distance:
2x+3(70)=320
x=55
