Wheels, Wheels and More Wheels!K-3 Problem Mr. Smith owns a bicycle shop where he builds and repairs bikes, trikes and unicycles. One day, he received an order from a customer for some wheeled vehicles. However, the customer did not tell him how many of each type of vehicle to build. The order only said 24 wheels were needed. Mr. Smith tried to contact the customer, but has not been able to reach him. In an attempt to be proactive, Mr. Smith wants to present as many options to this customer as possible. He needs to figure out how many different ways he can fill this order. Help Mr. Smith by making as many plans as you can that use all 24 wheels.
7-9 Problem
Your family has just bought a new car with an EPA highway rating of 15 kpl (kilometers per litre). The gas tank holds 60 litres of gasoline. You are planning a trip to St. John's, Newfoundland, which is approximately 6 125 km from Calgary. Assume your are driving mostly on a highway and a constant rate of speed--100 km per hour. How much gasoline will you need for the entire trip (there and back)? Gasoline cost, on average, $1.20 per litre. How much will you need to budget for fuel? How many hours will it take to make the trip, assuming you average 8 hours of traveling time each day? How often will you need to stop for gas? Each stop takes about 30 minutes to complete (snacks/bathroom breaks, etc.). You could take a different car that has an EPA highway rating of 12 kpl (kilometers per litre), but it only has a 50L tank. How would taking this car change the cost and the amount of time required to get to Newfoundland?
