Tom [10]

Answer:

$Speed = 21.43m/s$

Step-by-step explanation:

Given

$Distance = 1200m$ -- of the roadworks

$Time\ Recorded = 56s$

Required

Determine the speed

In this case:

$Speed = \frac{Distance\ of\ Roadword}{Time\ Captured}$

$Speed = \frac{1200m}{56s}$

<em></em> $Speed = 21.43m/s$ <em> --- approximated</em>

The equation of a line that goes through the points (0,0) and (300000,365)

olga_2 [115]

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~ 0 &,& 0~) 
% (c,d)
&&(~ 300000 &,& 365~)
\end{array}
\\\\\\
% slope = m
slope = m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{365-0}{300000-0}\\\\\\ \cfrac{365}{300000}\implies \cfrac{73}{60000}$

$\bf \stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-0=\cfrac{73}{60000}(x-0)\implies y=\cfrac{73}{60000}x$
