It's a scale factor of 3. the way you find out is by counting from the center point to an edge point on the orignal. then do the same on the scales one. now divide the scaled one by the orignal and bam you get the answer
DONT look at that photo. You have no idea what's in that link!
The answer is d) 6 batteries
They will be 15 miles apart after one hour if they left the same point at the same time.
<h3>How do we measure and calculate the distance in Geometry?</h3>
The distance between two points in geometry can be calculated by using the Pythagoras theorem.
Mathematically, the Pythagoras theorem can be expressed as:
where;
- x and y are opposite and adjacent sides respectively.
d = 15 miles
Therefore, we can conclude that they will be 15 miles apart after one hour if they left the same point at the same time.

Answer:
Her centripetal acceleration during the turn at each end of the track is
Step-by-step explanation:
Total distance covered in one round , D= 400 m
Time taken to cover one round , T = 1 min 40 s = 100 sec
Speed of runner ,
Now centripetal acceleration is given by
where
Thus her centripetal acceleration during the turn at each end of the track is
