How do I find miles per hour when I get minutes and miles
Scilla [17]
In this case you have:

\frac{miles}{minute}

An hour has sixty minutes.

\frac{60 minutes}{1 hour}

<span>You must multiply by this equality.

</span>(\frac{miles}{minute})(\frac{60 minutes}{1 hour})=\frac{(miles)(60 minutes)}{ (minute)(hour)}=\frac{(miles)(60)}{(hour)}


<span>You must multiply by 60 and you can convert miles per minute to miles per hour.</span>

BRAINLIESTTT ASAP! PLEASE HELP ME :)
MaRussiya [10]

Answer:

(11, -13)

Step-by-step explanation:

A is at (3, -5) and B is at (13, -15)

A point that is ⅘ of the way from A to B also divides the differences of the x-and y-coordinates in the same ratio.

For the x-coordinate,

x₂ - x₁ = 13 - 3 = 10

⅘ × 10 = 8  

 3 + 8 = 11

The x-coordinate of the point is x = 11.

For the y-coordinate,

y₂ - y₁ = -15 - (-5) = -15 + 5 = -10

⅘ × (-10) = -8

-5 + (-8)  = -13

The y-coordinate of the point is at y = -13.

The coordinates of the point are then (11, -13).

The diagram below shows the point ⅘ of the way from A to B.
