the process of rust

 

The process of rusting is when you leave a metal to face the elements, mainly water and wind. This causes rust which is the process of a metal going old and eaten away by a substance called rust or iron oxide. To create rust you need water and air these mix to cause the metal to be eaten away by rust. Rust is a reddish brownish colour and there are some metals that don’t rust like stainless steel. Iron oxide breaks the bonds between the metal and replace them with rust. It might take a long time but some metals will rust.

Problem: Jacks car can travel 15km per litre of petrol. He leaves Dubbo with 30 litres of petrol in his car and drives towards maitland. Which town will he be closest to when he runs out of fuel.

Dubbo-200km-Wellinngton-100km-mudgee-150km-singleton-200km-maitland

Preidct: I thought this would be a bout multiplication and addition.

Clarify: I had nothing to clarify

Find the big question: What town will he end up closest to.

Solve:

  1. First I multiplied 15 by 30 because he had 30 litres of petrol in his car and he goes 15km with every one litre. I got the answer of 450 so that means he could travel 450km.
  2. Then I looked at the map and added and added all the kilometres and I got the answer of Singleton

Dubbo-200km-Wellinngton-100km-mudgee-150km-singleton-200km-maitland

so he made it all the way to singleton

 

Summary: I got my prediction right and I I used the “have I seen a similar problem”.

100 wc week 33

It was a cold night as black as when you close your eyes, and the only thing I remember was my best friend running, Joe, alongside me and my dog, Bobby. During that time the only thing that I remember is when I approached the gateway and a dark figure approached he was nearly 18 feet tall. He spoke in a dark voice and said.

“Greetings I am Fred the 18 foot tall guy that guards this doorway.”

Me and my friend ran off at the speed of light and we didn’t stop until we ran all the way home.

Question: Each letter represents a different digit  from 1-9. If R=8 what number does FOUR equal.

TWO

+TWO=

FOUR

Predict: I thought this would be about addition.

Clarify: I had nothing to clarify

Find the big picture: what does the FOUR represent.

Solve:

1.first I looked at the 2 O’s then I knew that r=8 so the O is 4

TWO

+TWO

FOUR=8

2. Then I thought that the W could be a 1 and the U is 2.

TWO

+TWO

FOU=2 R=8

3.Because the FOUR has more letters than TWO the T has to be 5 or over. I made the T a 7 so I got the answer 1428

TWO

+TWO

F=1 O=4 U=2  R=8

Summary: My prediction was correct and I used the guess check and improve strategy.
