Final answer:
Sarah has 4900 meters remaining to run in the 5k race after stopping to drink water, having completed 100 meters so far.
Step-by-step explanation:
Sarah is participating in a 5k race, which is equivalent to 5 kilometers or 5000 meters. After starting the race, she takes a break to drink some water after running 100 meters. To calculate the distance left for her to run, we subtract the distance she has already covered from the total distance of the race. So, we do the following calculation:
- Total distance of the race in meters: 5000 m
- Distance Sarah has run: 100 m
- Distance remaining: 5000 m - 100 m = 4900 m
Therefore, Sarah has 4900 meters left to run in the race.
