Answer 2

Answer: 2.016 km per week

Explanation:

Given expression : 1200 cm per hour

We know that
`1\text{ km}=100000\text{cm}\\\\\Rightarrow\ 1\text{ cm}=(1)/(100000)\text{ km}`

Also,

`1\text{ day}=24\text{ hours} \\\\\Rightarrow\ \text{1 week}=7*24\text{ hours}=168\text{hours}\\\\\Rightarrow\ \text{1 hour}=(1)/(68)\text{ week}`

`\text{ 1200 cm per hour}=(1200)/(100000)*(1)/((1)/(168))\\\\=(1200)/(100000)*168=2.016\text{ km per week}`
