This year’s Christmaths Advent Calendar will have a question for every day in December up to and including Christmas Day, each one featuring a new mathematical challenge.
The star at the top of this Christmas tree flashes seven times in one minute.
Use your calculation skills to work out the following.
How many flashes will take place in:
- 20 minutes
- 1 hour
- 1 day
- 1 week
- Between December 10th and December 25th
- What if the light remained working for a whole year… how many flashes would there be?
- The bulb is guaranteed to last for 50,000 flashes. How many bulbs would you need to keep the star lit for a whole year?
