.
0.5×t=600
t=1200 minutes
Convert this time to hours by dividing by 60: 1200÷60=20 hours.
Alternatively, you could convert first:
hr
0.5m
3
×60min=
hr
30m

Next, use the standard work equation:
30 t = 600
t = 20 hours
Answer:
6.2
Step-by-step explanation:
You can find the median by adding up all of the numbers and dividing the result by how many numbers there are.

3x + x = 376
4x=376
x=94
Number of student tickets sold = 94 * 3 = 282
Number of adult tickets sold= 94
The correct answer should 1.1333
