The main formula used in work-rate, distance-speed problems is:
Work=Rate*Time, or Distance=Speed*Time.
Thus, the time is:

.
In our problem, the total distance is 3 km + 3 km = 6 km.
the total time is 20 min + 25 min = 45 min.
60 minutes are 1 hour, then
45 minutes are

Thus, the average speed is : distance/time = 6 km/ 0.75 h = 8 km/h
Answer: 8 km/h
Answer:
11,000 paid $14 for reserved seats.
25,000 paid $6 for general admission.
Step-by-step explanation:
<u>First, we need to establish the system of equations:</u>
x= number of people that pay $14
y= number of people that pay $6
14*x + 6*y= $304,000
x + y= 36,000
<u>Now, we isolate x in one equation and substitute it in the other one:</u>
x= 36,000 - y
14*(36,000 - y) + 6y = 304,000
504,000 - 8y = 304,000
200,000 = 8y
25,000 = y
x= 36,000 - 25,000
x= 11,000
11,000 paid $14 for reserved seats.
25,000 paid $6 for general admission.
