Final answer:
After converting the distances walked from meters to kilometers, Ramon has walked 0.997 km so far. Subtracting this from the total hike distance of 7 km, he still needs to walk 6003 meters to complete the hike.
Step-by-step explanation:
Ramon began a 7-km hike and walked 453 m on Monday, and 544 m on Wednesday. To find out how much he needs to walk to complete the hike, we need to first convert the distance he has walked into kilometers and then subtract that from the total hike distance.
First, we convert meters to kilometers by dividing by 1000, as there are 1000 meters in a kilometer.
- 453 m = 0.453 km
- 544 m = 0.544 km
Add the distances walked in kilometers:
0.453 km + 0.544 km = 0.997 km
Ramon has walked a total of 0.997 km so far.
To find out how much he still needs to walk, subtract this from the total hike:
7 km - 0.997 km = 6.003 km
Finally, convert this back into meters:
6.003 km × 1000 = 6003 m
Ramon still needs to walk 6003 meters to complete his hike.
