A speed camera takes two photographs of a car. Photo 1: 0.8m
Photo2: 0.8m

Photo 2 was taken 0.5 seconds after Photo 1.
Marks on the road are 0.8 metres apart.

Calculate the average speed of the car in m/s.

0.8m/0.5s = 1.6 m/s

i hope helps you

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
