Task (remember you can post your solution in the comments below):
The star at the top of a 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?
