Question

Peter is a long distance runner. In a training session he runs around the 400 m track 23 times. He wanted to run a distance of 10 km. How many more times does he need to run around the track to achieve this?

Answer 1

Answer:

2

Step-by-step explanation:

Currently, Peter has run a total distance of $400\cdot 23 =9200\:\text{m}$. His goal is 10 km, as stated in the problem, which equates to 10,000 meters. Thus he will need to run $10,000-9,200=800$ more meters to achieve his goal. Since the track is 400 meters, he needs to run around the track $\frac{800}{400}=\boxed{2}$ more times to achieve his goal.
