Answer:

Difference in speed = 10.28 miles/hour

Step-by-step explanation:

Whovenile Delinquents takes 32 minutes to hike up a mountain and 3 minutes to hike down a mountain.

Distance hiked = 3000 feet

We have to find the speed difference of climbing in both the journeys in miles/hour.

Conversions :

1 mile = 5280 feet

therefore 3000 feet = 0.57 miles

1 hour = 60 minutes

32 minutes = 0.53 hours

3 minutes = 0.05 hours

Speed = $\frac{distance travelled}{time}$

Speed uphill = $\frac{0.57}{0.53}$

Speed uphill = 1.08 miles/hour

Speed downhill = $\frac{0.57 miles}{0.05}$

Speed downhill = 11.36 miles/hour

Difference in speed = 10.28 miles/hour

Complete question :

Jeremiah plans on building a 5 meter long garden walkway that is paved with square stones that measure 5/6 meter on each side. There will be no spaces between the stones. How many stones will be needed to complete the garden walkway?

Answer:

12

Step-by-step explanation:

Given that :

Side length of square stone = 5/6 m

Length of walkway = 5 meter on each side

Total length = 2 * 5 = 10 meters

Therefore, number of stones required equals :

(Length of walkway / length of square Stones to be used)

10 meters ÷ 5/6 meters

(10 * 6 /5)

= 60/5

= 12 square stones

A line segment has (x1, y1) as one endpoint and (xm, ym) as its midpoint. Find the other endpoint (x2, y2) of the line segment i

Levart [38]

Answer: (a) ( $x_{2},y_{2}$ ) = (3,2)

(b) ( $x_{2},y_{2}$ ) = (19,-7)

Step-by-step explanation: Midpoint of a segment is halfway between 2 endpoints. It is calculated using the formulas:

$x_{m}=\frac{x_{1}+x_{2}}{2}$

$y_{m}=\frac{y_{1}+y_{2}}{2}$

Isolating $x_{2}$ :

$2x_{m}=x_{1}+x_{2}$

$x_{2}=2x_{m}-x_{1}$

And $y_{2}$ :

$2y_{m}=y_{1}+y_{2}$

$y_{2}=2y_{m}-y_{1}$

(a) Replacing values and calculating $x_{2}$ :

$x_{2}=(2*2)-1$

$x_{2}=3$

Calculating $y_{2}$ :

$y_{2}=[2*(-1)]-(-4)$

$y_{2}=2$

$(x_{2},y_{2})=(3,2)$

(b) $x_{2}=(2*5)-(-9)$

$x_{2}=19$

$y_{2}=(2*6)-19$

$y_{2}$ = -7

$(x_{2},y_{2})=(19,-7)$
