Question

1200 cm per hour= ? Km per week

Answer 1

Answer: 2.016 km per week

Step-by-step explanation:

Given expression : 1200 cm per hour

We know that $1\text{ km}=100000\text{cm}\\\\\Rightarrow\ 1\text{ cm}=\dfrac{1}{100000}\text{ km}$

Also,

$1\text{ day}=24\text{ hours} \\\\\Rightarrow\ \text{1 week}=7\times24\text{ hours}=168\text{hours}\\\\\Rightarrow\ \text{1 hour}=\dfrac{1}{68}\text{ week}$

$\text{ 1200 cm per hour}=\dfrac{1200}{100000}\times\dfrac{1}{\dfrac{1}{168}}\\\\=\dfrac{1200}{100000}\times168=2.016\text{ km per week}$
