Bike speed of 21miles per hour. What is the speed per minute how many miles will the cyclist travel in 10 minutes

Answer:

<em><u>First part: </u></em><em><u>0.35 miles per minute</u></em>

<em><u>Second part: </u></em><em><u>3.5 miles in 10 minutes</u></em>

Step-by-step explanation:

<em>Think about this as a fraction. Fractions can't be added nor subtracted unless they share the same denominator.</em> So for this case, we have to turn hours into minutes. So 21 mph becomes 21 miles per 60 minutes. Then, we divide 60 from each side to find the speed per minute. 21/60 = 0.35, so the answer to the first part is <u>0.35 miles per minute</u>.

<u>Using what we got</u>, we can answer the second part of the distance covered in 10 minutes. So, we just <em><u>multiply</u></em> 0.35 by 10 which is <u>3.5 miles covered in 10 minutes</u>.

Answer: 3.61km or √13

Step-by-step explanation:

Given Data:

Sides of hexagon = 2km each

Distance walked by Ama = 5km

Therefore;

Let Ama starting position be the origin.

With this She would travel along two edges and then go halfway along a third.

Her new x- coordinate would be

= 1 + 2 + 1/2 = 7/2

Because she travels a distance of 5km which translates to 2 and half side of the Hexagon

= 2*1/2

= 1km. On her x-coordinates

For her y-coordinate we use same principles as x-coordinates

= √3 + 0 - √3/2

= √3/2

Therefore her distance walked

= √ ( (7/2)^2 + (√ 3/2)^2 )

= √ ( 49/4 + 3/4 )

= √ 13

= 3.61km

Answer:

D = .44P

Step-by-step explanation:

We need to find the slope of the line

m = (y2-y1)/ (x2-x1)

Using two points

m = (22-4.4) /(50-10)

   = 17.6/40

   = .44 lb/ in^2 ft

We can use the point slope form of the equation

y-y1 = m(x-x1)  where y=D and x=P

D-4.4 = .44 (P-10)

Distribute

D-4.4 = .44P - 4.4

Add 4.4 to each side

D -4.4+4.4 = .44P -4.4+4.4

D = .44P
