Solve the following on loose leaf paper.
1.) Mr. C and Mr. M are having a hot dog eating contest. Mr. C ate 10 hot dogs in 4 minutes. Mr. M ate 13 hot dogs in 5 minutes.
Who is eating the hot dogs at a faster rate? If they kept eating the same amount, without getting full or sick, how many would each eat in 20 minutes? How many minutes does it take for each of them to eat 1 hot dog?
2.) FoxConn is the company that manufactures the iPhone for Apple. They make 400,000 iPhones per day. If they make 400,000 iPhones per day, how many are they making per hour? How many per minute? How many per second?
How many minutes does it take them to make 1 iPhone
(Hint: your unit rate will be X minutes / 1 iPhone)
3.) Mr. M is trying to decide between two printers. The HP printer can print out 300 black-white copies in 5 minutes and 40 color copies in 5 minutes. The Dell printer can print out 250 black-white copies in 4 minutes and and 50 color copies in 8 minutes. Which copier should Mr. M purchase? Justify your answer with mathematical facts.
