Answer:
85 adult tickets
150 children tickets
Step-by-step explanation:
we can write a system of equations and then use the 'elimination method':
let a = adult tickets
let c = children tickets
a + c = 235
5a + 2c = 725
we can multiply the first equation by -5 to get:
-5a - 5c = -1175
now we can add the second equation to get:
5a + 2c = 725
-3c = -450
c = 150
a + 150 = 235
a = 85

Answer:
310.6m^3
Step-by-step explanation:
10 minutes at 2 meters/second
1 minute = 60 seconds
10 minutes = 600 seconds.
600 seconds at 2 meters/second
2 meters × 600 = total distance
