Final answer:
Chris has 5,000 meters left to run in the 20-kilometer race after completing ¾ of the course.
Step-by-step explanation:
The student is asking how many meters are left for Chris to run in a 20-kilometer race if he has completed ¾ of the course. To find the answer, we start by calculating ¾ of 20 km:
¾ of 20 km = 20 km × ¾ = 15 km.
Since Chris has completed 15 km, we need to determine the remaining distance he has to run. This is done by subtracting the distance completed from the total distance:
20 km - 15 km = 5 km.
To convert the remaining distance from kilometers to meters, we use the conversion factor that 1 km is equal to 1,000 meters:
5 km × 1,000 m/km = 5,000 m.
Therefore, Chris has 5,000 meters left to run.
