L.O: I can solve problems that involve mixed operations.

Beth wyt ti'n meddwl?
Talk to your partner time...
You are going to anayse and evaluate some data on the Fayre.
How much power is needed to run the rides?
How much energy is used?
Choose your chilli and find out...
Gwyrdd Chilli:
1. Which ride uses the most power?
2. What is the difference in power between the roller coaster and the Ferris wheel?
3. Which ride lasts the longest? How long does it last?
4. Which ride uses the least energy?
5. If we wanted to save electricity, which ride should we run less? Why?
6. Which rides use the same amount of energy as another?
7. How many times can the Ferris wheel be used in half an hour?
8. I went on bumper cars, the carousel and the drop tower. How much energy has this used?
Oren Chilli:
1. Which ride uses the most power?
2. Which ride runs for the longest time?
3. Which ride is the most energy-efficient? (Uses the least energy for the most time)
4. What is the difference between the power of the roller coaster and the bumper cars?
5. If the fairground only has 1,000 Watts of electricity for one hour, what rides could be run at the same time without running out of power? Is there more than one possible combination?
6. How many times could I go on the Ferris wheel in an hour?
7. I want to go on each ride once. How long will I need to be at the Fayre for?
8. What is the range for the energy used?
Coch Chilli:
1. Which ride is the most energy-efficient? (Uses the least power for the longest time)
2. What is the range for power?
3. What is the range for energy used?
4. What is the mode for voltage?
5. What is the total power for all the rides at the Fayre?
6. I go on the bumper cars once and the Ferris wheel twice. What can I still fit in if I only have half an hour at the Fayre?
7. If we wanted to reduce electricity use, which ride should run for a shorter time? Why?
8. Which ride uses the most energy per minute? (Bus stop maths)
9. I have 1 hour at the Fayre. I will have a 15 minute break for food. I need to allow 15 minutes for queueing. I want to go on each ride at least once. Is this possible? Plan it out and see. Will I have any time left or is it not possible?
Using the examples above create your own Fayre ground questions from the electricity data for your chilli.
