8.5cm · 250,000 = 2,125,000cm
1m = 100cm therefore 1cm = 0.01m
2,125,000cm = 2,125,000 · 0.01 = 21,250m
1km = 1,000m therefore 1m = 0.001km
21,250m = 21,250 · 0.001km = 21.25km
Answer: 21,250m = 21,25km
Answer: There are 4 average cars in the system.
Step-by-step explanation:
Since we have given that
Arrival rate = λ = 4 cars per hour

So, Average number of cars would be
So, it becomes,
Hence, there are 4 average cars in the system.
