Answer:
∴73,563 calls are made between two cities with populations of 100,000 and 160,000 that are 435 miles apart.
Step-by-step explanation:
Given that,
The number of phone calls between two cities (N )
- directly proportional as the value of populations
and
of two cities.
- Inversely varies as the magnitude of distance (d).
Given that,
N=18,000, d=310 miles, =15,500 and
=180,000
Now,
N=? , d=435 miles, =100,500 and
=160,000
∴73,563 calls are made between two cities with populations of 100,000 and 160,000 that are 435 miles apart.
