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.
