The Desk Duck Visits Brazil

Mrs. Krall took our desk duck with her on her trip to Brazil. Check out the fun things they did together and post your answers to the math problems below.

 

1 Real (R$1) is equivalent to 60 cents. Each candle is 6 Reals (R$6). How much is that in American dollars?

 

1 kilogram is equivalent to 2.2 pounds. One bag of dried sugar cane is ½ of a kilogram. How many pounds are in each bag?



 

Each bag of dried mangoes costs R$4 or 3 bags for R$9. Which is the better deal and what is the ratio of bags to Reals when you buys 3 bags?

 

Fahrenheit is equal to the Celsius temperature x 9/5 + 32.
At the Japanese Garden, the water is 20 degrees Celsius at 3pm. Using the formula 20 x 9/5 + 32, what is the temperature in Fahrenheit.

 

At 5pm, the water was 15 degrees Celsius. Using the formula 15 degrees Celsius x 9/5 + 32, what was the temperature in Fahrenheit?

 

This Pagoda has 3 levels that are 2 meters each. If 1 meter equals 3.3 feet, how tall is the Pagoda in feet?

 

This bridge is 2 meters long. Using the formula: 1 meter = 3.3 feet,
How long is the bridge is feet.


 

The cost to get into this Brazilian Museum is $5.10 in Americam money. If 1 American dollar is equal to 1.7 Reals, how many Reals does it cost to get into the musuem?


 

The duck decided to try some coconut juice. It drank 100ml of coconut juice. If 50ml = 1.7 oz., how many ounces did the duck drink?


 

Ooops!!! The duck drank too much, but had a wonderful time in Sao Paulo and Caldas Novas Brazil!

Desk Duck Travels to India!

 

 

For lunch on our first day in India, I had a dosa which cost 39 rupees and my mom got a mini meal which cost 98 rupees. If 45 rupees equal around 1 U.S. dollar, then how much did our meals cost?

 

On our day in Delhi we took a Taxi to the Taj Mahal. It took us 5 hours to get there and 4 hours 30 minutes to get back. The driver cost us 7,000 rupees which equals how many U.S. dollars? When we arrived they had closed for the day so we went on the back side of the Taj Mahal across the Yumana river to see it. Then we went to the hotel and decided to rush over in the morning. One ticket for someone outside India cost 750 rupees to go inside the Taj Mahal, and one ticket for someone living in India cost 20 rupees. How much does that cost in U.S. dollars?




It took us 45 minutes to get in but the wait was worth it. The sight was amazing there were so many details such as carvings, embroidering and gems, plus it was all made out of white marble. Unfortunately we had to leave early to catch our plane to Combitore.

 

On our last day, our flight from Chennia to Chicago left at 4:30am on the 31st of December and arrived at 4pm on the 31st of December. The time difference from the U.S. to India is 11 ½ hours. So how long was the flight?
