Answer:
Step-by-step explanation:
I'm assuming you mean how many mph when you refer to how fast the car was going.
So 300 km = 1.5 hrs
1.) Find the number of km per hour
Since we have the equation 300km = 1.5hr, we can just divide 1.5 (to isolate the number of hours) on both sides.
You should get 200 km = 1 hour
2.) Convert km to miles
To do this, you must know the conversion 1 km = 0.621371192 miles
So to convert 200 km to miles, just multiply 200 x 0.621371192.
You should get 124.274238.
That means the Ferrari drove at a pace of roughly 124 mph :)
Since there is two negative signs in the original equation, you need two negative signs in the equivalent one as well.
Because one of the negatives if before the fraction, it doesn't matter if the second negative is on the 13 or on the 12.
The answer is A.
Answer:
The slope of the line is -5
Answer:
The playground is 160ft by 360ft.
The model is 4in by 9in
First, 1ft = 12 inches.
Then the measures of the playground, in inches, is:
160*12in = 1920 in
360*12in = 4320in
The playground is 1920in by 4320in.
Then, the ratios between the measures of the playground and the model are:
1920in/4in = 480
4320in/9in = 480
This means that each inch in the model, represents 480 inches in the actual playground.
