1. Mickey Mouse is on a plane that can fly from Chicago to his movie set in L.A. - a distance of 2000 miles - in 4 hours against a 50 mph wind. His return flight home only took 3 1/3 hours. What was the speed of Mickey's plane in still air? (HINT: Set up a chart)
2. Minnie Mouse makes $100,000 for a 30 minute movie. How much money would she make from starring in a 2 hour movie? (HINT: set up a direct proportion)
3. Donald Duck is confused in math class. He got an answer of three after working this problem:
7 + x + 4 Why is this wrong?
x - 3 x - 3
4. Daisy got a new pool. She wants to fill it before it gets too hot outside. Her pool can be filled by the main hose in 6 hours. There is also a smaller hose that can fill the pool in 9 hours. There is a drain that can drain the pool in 12 hours. If she runs all of these at the same time, how long will it take to fill her pool?
5. Goofy thinks that the problem
1 + 1
x + 5 x - 3
2x squared - 3x - 5
x squared + 2x - 15
looks goofy. Help him simplify it.
