Chapter 6, Problem 15MCQ

a.

To determine

Height if Mt McKinley in meters.

Answer to Problem 15MCQ

Height if Mt McKinley in meters is 6254.496 m

Explanation of Solution

Given:

Height of Mt McKinley is 20520 ft.

Height of saint alias is 18008 ft.

Height of Foraker is 17400 ft.

It is known that 1 ft = 0.3048 m

Therefore,

  $\begin{array}{l}20520\text{ ft = 20520}\times \text{0}\text{.3048 m}\\ \text{=6254}\text{.496 m}\end{array}$

Therefore, height of Mt McKinley in meter is 62254.496 m.

b.

To determine

Total height of all three mountains in yard.

Answer to Problem 15MCQ

Total height of all three mountains in yard is 18617.364 yard.

Explanation of Solution

Given:

Height of Mt McKinley is 20520 ft.

Height of saint alias is 18008 ft.

Height of Foraker is 17400 ft.

Let total height of all three mountains is h,

  $\begin{array}{l}h=20520+18008+17400\\ =55908\text{ ft}\end{array}$

It is known that 1 ft = 0.333 yard

Therefore,

  $\begin{array}{l}55908\text{ ft = 55908}\times \text{0}\text{.333 yard}\\ \text{=18617}\text{.364 yard}\end{array}$
