Question

A baby whale was growing at an average rate of 250 pounds per day. What is the equivalent of this rate in ounces per hour?

Answer 1

16 ounces=1pound
1 day=24 hours

Answer 2

250 divided by 24= pounds per hour then you take the answer from that and divide it by 16 and you will know how many ounces it grows every hour.

Answer 3

Thank you

Answer 4

Write each conversion factor as a fraction that equals 1.
Then multiply the given number by the conversion factors that will cancel out the unwanted units and will keep the desired units.

Answer 5

Here is an example.
What is 50 miles per hour in feet per second?

1 mile = 5280 ft

\(\dfrac{1~mile}{5280~ft} = \dfrac{5280~ft}{1~mile} = 1\)

1 hour = 3600 seconds

\(\dfrac{1~hour}{3600~seconds} = \dfrac{3600~seconds}{1~hour} = 1\)

Answer 6

Now that we have the conversion factors, we use the appropriate ones:

\(50 \dfrac{\cancel{miles}}{\cancel{hour}} \times \dfrac{5280~ft}{1~\cancel{mile}} \times \dfrac{1~\cancel{hour}}{3600~seconds} \)

Notice that the only units left are ft/sec.
The answer is
\(73 \dfrac{1}{3} \dfrac{feet}{sec} \)

Answer 7

250 pounds per day=250*16=4000 ounces per day=4000/24=500/3=166 1/3 ounces per hour

Answer 8

\(250\dfrac{lb}{day} \times \dfrac{16~oz}{lb} \times \dfrac{1~day}{24~hours} \)

\(=250\dfrac{\color{red}{\cancel{lb}}}{\color{green}{\cancel{day}}} \times \dfrac{16~oz}{\color{red}{\cancel{lb}}} \times \dfrac{1~\color{green}{\cancel{day}}}{24~hours} \)

\(= 166 \dfrac{2}{3} \dfrac{oz}{hour}\)
