WEEK 3: Up, Up and Away
DAY 2: The Air Up There
Activity 3: Flying Fungi [10 points]
In the middle of winter it can get quite wet and damp in New Zealand, can’t it? When it gets really damp, it is common for things like mould and fungi to start to grow. We can often see them on the walls, ceilings or floors of our houses or outside on footpaths, buildings or roadways. Some types of mould and fungi are so small that they can’t be seen. Some of these tiny fungi/moulds can be found in the air. They are called ‘airborne fungi’ and they can be unhealthy for us.
Let’s imagine that we tested the air in your classroom and found 7 different kinds of mould. Eek! The cleaner says that it takes 5 days for each mould to be eradicated (removed). If the school had to remove each mould one at a time, how long would it take to remove all the mould from the classroom?
On your blog, tell us how you would solve this tricky maths problem. Be sure to also post your final answer in days or weeks.
The final answer to the question is 35 days.
Hi Lyan,
ReplyDeleteI can see you have shown three different ways to solve this problem - nice work!
That mould looks horrible - it's so important to keep places aired out and dry otherwise mould might grow there!
I'm enjoying reading your blog posts!
