PROBLEM:
Ana began a 5-km hike on Monday by walking 490 m. She walked 3 km on Tuesday and 546 m on Wednesday. How many meters must she walk to complete the hike?
SOLUTION:
- Convert first the given meters into kilometer..
[tex]490m = 0.49 km[/tex]
[tex]546m = 0.546 km[/tex]
- Add the two converted kilometers.
[tex]0.49 + 0.546 = 1.036 km[/tex]
- Then, add the 3km to the sum of two converted kilometers.
[tex]1.036km + 3km[/tex] = 4.036km
[tex]\bullet[/tex] Ana walked 4.036 kilometers, to get the remaining meters she must walk to complete the hike, subtract the total distance of her walk from the distance she must walk.
[tex]5km - 4.036km[/tex] = [tex]0.964[/tex] km
[tex]\bullet[/tex]0.964 in meter is 964.
ANSWER:
Ana must walk 964 more meters in order to complete the hike.
