### Answers to Billy's quiz of 3-13-2013

Here are the questions.  Billy and I will post the answers tomorrow morning.

1. A bus trip starts 9:15 in the morning and ends at 4:25 in the afternoon.  How long was the bus trip?
2. A person has four cups and four pints of milk.  If he poured all of the milk into one gallon jug what percent of the jug would be filled up?  Also, how many fluid ounces of milk does he have (There are 8 fluid ounces in one cup of milk.)
3. How much is 5 1/2 tons in pounds?
4. How much is 160,000 ounces in tons?

Here are the answers and the logic:

Problem 1:

9:15 to 10 is 45 minutes
10 to 12 is 2 hours.
12 to 4 is 4 hours
4 to 4:25 is 25 minutes

Add  6 hours 70 minutes or 7 hours 10 minutes

Problem 2

four cups is two pints so four cups + four pints is 6 pints or 3 quarts which is 3/4 of the gallon jug.

6 cups x 8 fluid ounces is 48 fluid ounces

Problem 3:

there are 2000 pounds per ton.  5 1/2 x 2000 = 11,000 tons.

Problem 4:

160,000 tons divided by 16 ounces per ton is 10,000 pounds.  10,000 pounds divided by 2000 pounds per ton is 5 tons.

Note as check 5 tons x 2000 pounds per ton is equal to 10,000 pounds.  10,000 pounds x 16 ounces per pound is equal to 160,000 ounces.

Practice is essential to learning math!!!!  I hope this was of some interest and use.
