Question

A hike starts at an elevation of 13 4/5 feet below sea level and ends at an elevation that is 1542 feet higher.How high was the hiker in feet above sea level at the end of the hike.

1528
1528 1/5
1555
1555 4/5

Answer 1

Treat "13 4/5 feet below sea level" as a negative quantity. Then add the increase, "1542 feet," obtaining

(1542 - 13 4/5) feet = 1528 1/5 feet above sea level.

Answer 2

Answer: Second option is correct.

Explanation:

Since we have given that

Distance a hike starts below sea level is given by

`-13(4)/(5)\\\\=(-69)/(5)`

( we used "negative sign" as it is below the sea level)

Distance a hike starts higher is given by

`1542\ ft`

According to question,

Total distance the hiker was above sea level at the end of the hike is given by

`1542-(69)/(5)\\\\=(7710-69)/(5)\\\\=(7641)/(5)\\\\=1528(1)/(5)\ ft`

Hence, Second option is correct.
