Explanation:
A worker at a mill is loading 5-lb bags of flour into boxes to deliver to a local warehouse.
Each box holds 12 bags of flour.
Pounds of flour per box
x = 12 × 5 lb = 60 lb
We need to multiply by the conversion rule
1 T = 2000 lb
Find out how many pounds are in 3 tons. Pounds of flour in the warehouse.
y = 3 T × 2000 lb = 6,000 lb
Divide by the number of pounds per box. 100 boxes are needed.

Question 4.
A science teacher needs to collect lake water for a lab she is teaching. The lab requires each student to use 4 fluid ounces of lake water. If 68 students are participating, how many pints of lake water will the teacher need to collect?
_____ pints

Explanation:
Find the total number of ounces the students use.
s = 68 × 4 oz = 272 oz
First, convert from ounces to cups.
1 c = 8 oz
Find how many cups are in 272 ounces
y = 272 oz ÷ 8 oz = 34 c
Now from cups to pints
1 pt = 2 c
Find how mant pints are in 34 cups
x = 34 c ÷ 2 c = 17 pt
18 pt – 17 pt = 1 pt
Thus 1 pint is leftover.

Find the start, elapsed, or end time.

Question 11.
Start time: 11:38 A.M.
Elapsed time: 3 hr 10 min
End time: _____ : _____ P.M.

Explanation:
You can use a number line or a clock to find the end time.
Add the hours to the start time.
12:38 pm
1:38 pm
2:38 pm
x = 2:38 pm + 10 min = 2:48 pm

Question 15.
_________
_________

Groove Box
Internet -C

Explanation:
From the above figure, we can observe that the Internet services downloaded the podcast in less than 4 minutes is Groove Box and Internet -C
Groove box took 173 sec and Internet-C took 196 seconds.
Convert from minutes to seconds
1 min = 60 sec
1 sec= 1/60 min
173 sec = 2 min 53 sec
196 sec = 180 sec + 16 sec = 3 min 16 sec

Question 16.
Which service took the longest to download the podcast? How much longer did it take than Red Fox in minutes and seconds?
Type below:
_________

Explanation:
The figure shows that Top Hat took the longest time to download the podcast.
Convert from minutes to seconds
1 min = 60 sec
1 sec= 1/60 min
1050 sec = 1020 sec 30 sec
1020 sec = 1020 × 1/60 min = 17 min
1050 sec = 17 min 30 sec.
To find how much time it took than Red Fox, we need to subtract the time from red fox and top hat.
1050 sec – 310 sec = 740 sec
Convert from seconds to minutes.
1 min = 60 sec
1 sec = 1/60 min
740 sec = 720 + 20 sec
720 sec = 720 × 1/60 = 12 min
740 sec = 12 min 20 sec

Question 17.
Which service was faster, Red Fox or Internet-C? How much faster in minutes and seconds?
Type below:
_________

Explanation:
From the above figure, we can see that Internet-C is faster than Red Fox.
Internet-C took 196 sec
Red Fox took 310 sec
310 sec – 196 sec = 114 sec
Convert from seconds to minutes.
1 min = 60 sec
1 sec = 1/60 min
114 sec = 60 sec + 54 sec
114 sec = 1 min 54 sec

Question 18.
Explain how you could find the number of seconds in a full 24-hour day. Then solve.
Type below:
_________

Convert from hours to minutes

Now convert from minutes to seconds.
1 min = 60 sec
1440 min = 1440 × 60 = 86400 sec
Thus a day has 86400 seconds.
