Isabelle runs 6 kilometres every morning. One day, she runs 0.66 kilometres and then stops to take a break. How much further does Isabelle have left to run?

Break Down the Problem

1. Determine the total distance Isabelle needs to run.
2. Find out how much distance she has already covered.
3. Calculate the remaining distance to run.

Relevant Concepts

• Total distance to run: 6 km
• Distance covered: 0.66 km

Analysis and Detail

1. Total Distance: Isabelle's goal is to run 6 km.

2. Distance Already Covered: After running 0.66 km, we can represent this distance as:

   $\text{Distance Covered} = 0.66 \text{ km}$

3. Remaining Distance Calculation: To find out how much further Isabelle has left to run, we subtract the distance covered from the total distance:

   $\text{Remaining Distance} = \text{Total Distance} - \text{Distance Covered}$ $\text{Remaining Distance} = 6 \text{ km} - 0.66 \text{ km}$

Verify and Summarize

Calculating the remaining distance:

$\text{Remaining Distance} = 6 - 0.66 = 5.34 \text{ km}$

Thus, Isabelle has 5.34 km left to run.

Final Answer

Isabelle has 5.34 kilometres left to run.
