Answer: Speed in miles per hour is 45 mph.
Step-by-step explanation:
Since we have given that
Distance covered = 15 miles
Time taken to cover the above mentioned distance = 20 minutes
We need to calculate the speed in miles per hour ,
As we know the formula for " Speed " i.e.
Now, we will put the value of distance and time in the above formula:
Hence, Speed in miles per hour is 45 mph.
B.) 85
They are alternate interior angles so they are the same degree.
So the radius is 7 inch which is given
Use the formula for the circumference which is 2xpiXradius
2x3.1415x7=44 to nearest integer
The perimeter of the square is given by:
Where,
x: square side.
Substituting values we have:
Rewriting the perimeter of the square we have:
Finally, dividing both values:
Answer:
the perimeter of the square is:
