If it takes 16 men, 5 hours to load a ship. How long will it take 24 men?
Show your workings out?

Work out how many man-hours it took.
If 16 men took 5 hours, then it took 16x5 = 80 man-hours.
So, if 24 men were there, then it would take 80÷24 = 3 hours, 20 minutes.
Why did the vector cross the road?
It wanted to be normal.

Many thanks, we have been at this for hours. I made this 3 hours 45 mins.
Can see how it is done now!

My 8 year old daughter has been told to measure the perimeter of 4 household objects. Surely you can only measure the area of 3D objects? You only measure perimeters when using 2D shapes?

Yeah, it doesn't make much sense to talk about the perimiter of 3D objects. However, an object like a ruler or a thin notebook with a tiny width can be thought of as 2D and one can measure their perimeter.
