Given:
Scott can run 20 km in 85 minutes.
To find:
How long will it take Scott to run 52 km?
Solution:
Let x be the number of minutes it will take him to run 52 km.
We know that,

Using this formula, we get
...(i)
...(ii)
Equating (i) and (ii), we get



Divide both sides by 20.


Therefore, it will take 221 minutes to run 52 km.

80+25+x=180
x = 75
Answer:
6x-24y
Step-by-step explanation:
Step 1: -30x-12y+36x-12y
Distribute-3 to 10x and 4y
Then distribute 6 to 6x and -2y
Step 2: 6x-24y
After that add up like terms
Answer:
w = 160, L = 50
Step-by-step explanation:
Length = 50 feet
Width = 160 feet
First Find the Length
w = l + 110
P=2w+2l
420=2w+2l
420=2(l+110)+2l
420=2l+220+2l
4l=200
l=50
Finding the Width
w=(50)+110
w=160
