Answer:
The maximum distance to the nearest kilometer between Westford and Centerville is 111.43 km.
Step-by-step explanation:
Local train stats:
Rate = 60 km/h
Distance = x km
Time = x/60 hours
Express train stats:
Rate = 80 km/h
Distance = km
Time = hours
Now we will equate both the times.
x = 83.57 km
km
Hence, the maximum distance to the nearest kilometer between Westford and Centerville is 111.43 km.
Answer: The number of child tickets is 85 and the number of adult tickets is 95.
Step-by-step explanation:
Let C = Number of child tickets
A = Number of adult tickets.
As per given, we have
C+A=180 (i)
7C+13A=1830 (ii)
Multiply 7 to both sides of equation (ii), we get
7C+7A=1260 (iii)
Eliminate (iii) from (ii) , we get
Put value of y in (i), we get
C= 85
Hence, the number of child tickets is 85 and the number of adult tickets is 95.
