(C)
Step-by-step explanation:
We are going to use the following conversions for this problem:
1 km = 1000 m
1 hr = 60 min
The key is to multiply the given quantity with factors such that the unwanted units cancel out, leaving only the ones we need. In this case, we need meters and minutes. The set up goes like this:
Answer:
The perimeter of △HFM is 50.75 units
Step-by-step explanation:
The picture of the question in the attached figure
In this problem
Triangles HFM and PST are similar
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional, and this ratio is called the scale factor
step 1
Find the scale factor
Let
z ----> the scale factor
substitute the given values
step 2
Find the perimeter of triangle PST
step 3
Find the perimeter of triangle HFM
we know that
If two figures are similar, then the ratio of its perimeters is equal to the scale factor
so
The perimeter of triangle HFM is equal to the perimeter of triangle PST multiplied by the scale factor
so
