The unit rate of boxes produced per hour by the machine is 1200 boxes per hour. This is obtained by multiplying the number of boxes made in 15 minutes (300 boxes) by 4 to account for the 4 15-minute intervals in an hour.
To find the unit rate of boxes produced per hour, we first need to determine how many minutes are in an hour. There are 60 minutes in 1 hour.
Then, we need to figure out how many 15-minute intervals fit into 60 minutes. To do this, we divide 60 by 15, which gives us 4. This means there are 4 15-minute intervals in an hour.
Given that the machine makes 300 boxes in 15 minutes, we multiply this quantity by 4 to find out how many boxes it makes in an hour. Therefore, the expression for the unit rate in boxes per hour is 300 boxes * 4, which equals 1200 boxes per hour.

Answer:
18 Runners finished the race
Step-by-step explanation:
Given in question
Number of runners taken part in race = 90
Now in first half , drpped
i.e = 36
so left runners in first half = 90- 36 = 54
again in second half 54 runners are there, but of them again dropped
So, = 36
Thus runner left in second half = 54 -36 = 18
Hence the number of runner finished the race = 18 Answer
Answer:
p = 48.2
Step-by-step explanation:
p = 2L + 2w
p = 2(8.3) + 2(15.8)
p = 16.6 + 31.6
p = 48.2
Answer:
P = 48.2 ft
Step-by-step explanation:
P =2l+2w
Given: l = 8.3 ft and w = 15.8 ft
Plug in
P =2(8.3) + 2(15.8)
P = 16.6 + 31.6
P = 48.2 ft
