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

2

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
`(800)/(400)=\boxed{2}` more times to achieve his goal.
