<h3>Hello There!!</h3>

<u>Given,</u>

Distance (d)= 2955 km

Time (t)= 13 hr

<u>To </u><u>Find,</u>

Speed (s)=?

<h2><u>Solution</u></h2>

s =  \frac{d}{t} \\   \\ s =  \frac{2995}{13}  \\  \\ s = 227.308  \:  \:  \text{km/hr}

Rounding To Nearest Whole Number= 227 Km/hr

\therefore \text{speed} = 227 \text{km/hr}

Answer:

As Per Provided Information

Distance travelled by the car is 2955 Km

and it takes 13 hours to cover that distance .

We have been asked to determine the speed of the car .

\boxed{\bf \: speed \:  =  \dfrac{Distance Travelled by Car}{Total Time Taken }}

substituting the value we get

\longrightarrow\sf \: Speed =  \dfrac{2955}{13}  \\  \\  \\ \longrightarrow\sf \: Speed =   \cancel\dfrac{2955}{13} \\  \\  \\ \longrightarrow\sf \: Speed =227.30 \\  \\  \\ \longrightarrow\sf \: Speed  \approx227 \: km {hr}^{ - 1}

<u>Therefore</u><u>,</u>

  • <u>Speed</u><u> of</u><u> the</u><u> </u><u>car </u><u>is </u><u>2</u><u>2</u><u>7</u><u> </u><u>Km/</u><u>hr.</u>

I REALLY NEED HELP!!! If someone can answer this quickly and correctly I will give them Brainliest. 1. What is the function rule
Rainbow [258]

Answer:

y= -4x + 3

Step-by-step explanation:

Because the slope is -4/1 which is the same as 4 and 3 is the y-intercept.

Here's the work;

We can just use the first two coordinates which are (0,3) and (1,-1) to get from the x-value 0 to 1 we add 1. and to get from the y-value 3 to -1 we subtract 4. Therefore the slope is -4 and the y- intercept (when x is zero) is 3. Pop that into slope intercept form to get y=-4x +3

Hope that helps and have a great day!
