Answer:
The car was travelling at a speed of 60 miles per hour.
Step-by-step explanation:
Given:
Distance traveled = 330 miles
Time Period = 
we need to find the speed of the car .
Solution:
Time Period = 
Now we can say that;

So Time period = 
Now we know that;
Distance traveled
is equal to Speed
multiplied by Time Period
.
framing in equation form we get;

Dividing both side by 5.5 we get;

Hence The car was travelling at a speed of 60 miles per hour.
Hello!
The equation can be written as seen below. You only need a y-intercept and slope to write the equation.
y=-2x+3 (it intercepts at a y-value of 3).
I hope this helps!
Below is an equation that shows the equivalency between meters andGigameters:

The conversion factor should be used to convert from meters toGigameters should be:
2x + 4(-6x + 12) = -84
2x - 24x + 48 = -84
-22x + 48 = -84
-22x = -84 - 48
-22x = -132
x = -132/-22
x = 6
hope this helps, God bless!
