Remark

He's very lucky to be alive.

Givens

distance = d = 0.8 miles

Rate = r   =       0.0321 mi per minute

Time = t = ??

<u>Formula</u>

d = r * t

<u>Solve</u>

0.8 = 0.0321 * t      Divide by 0.0321

0.8/0.0321 = t

t = 24.92 minutes  <<<< Answer

0.0321 miles per minute, simply means, in 1 minute, it does 0.0321 miles.


\bf \begin{array}{ccll}&#10;miles&minutes\\&#10;\cline{1-2}&#10;0.0321&1\\&#10;0.8&x&#10;\end{array}\implies \cfrac{0.0321}{0.8}=\cfrac{1}{x}\implies 0.0321x=0.8&#10;\\\\\\&#10;x=\cfrac{0.8}{0.0321}\implies x\approx 24.92211838

Steve ran 11 miles

let the distance Steve ran be x

Then distance Kevin ran is x + 4 ( 4 miles more than Steve )

x + x + 4 = 26 ( the sum of their distance is 26 )

2x + 4 = 26 ( subtract 4 from both sides )

2x = 22 ( divide both sides by 2 )

x = 11

Steve ran 11 mies and Kevin ran 11 + 4 = 15 miles

check 11 + 15 = 26

1) What is the slope of x+y=4?
Lerok [7]
1) y=-x+4, the slope is -1
2)y=-x+4, slope is -1
3) yes
4)It's the same line if the slopes and y-intercepts are the same, so the number of corresponding points are infinite.
