First we need to find Mia's speed (v) in km/min
v = distance travelled/ time
v = 3 km/20 minutes
v = 0.15 km /min
in order to convert the speed into mile/min, we need to use the conversion factor given in which for every kilometer, there is 0.6 miles.
v = 0.15 km/min *(0.6 miles/ km)
v =0.09 miles/min
therefore the speed in miles/min is 0.09 miles/min
Answer:
Graph 3.
Step-by-step explanation:
|x| + 3 > 7
|x| > 4
This means x > 4 or x < -4,
which is the third graph.
3a+4c=67
5a+6c=106
9a+12c=201
10a+12c=212
-a=-11
a=11
33+4c=67
4c=34
c=8.5
A=11; C=8.5
