Answer:
The trail on her new map is 8 cm
Step-by-step explanation:
Here, we are interested in knowing the the length of the trail on the new map.
The scale on her old map is 1 cm represents 100 m
While her new map has a scale of 1 cm to 500 m
Now, running a trail of 40 cm on her old map, we need to get the actual distance.
The actual distance will be 40 * 100 = 4,000 m
Now, we shall convert this to the new map scale
We simply convert this to cm in the new map scale by dividing the 4,000 m by 500 m
That would be 4,000/500 = 8 cm
So the trail on her new map is 8 cm
