Answer:
a. 9,235 feet
b. John Adam was older when he became president.
Step-by-step explanation:
(15). Height of the mountain = 29,135 feet
A climber hiked from base camp at 17,600 feet and then 2,300 feet.
He hiked total = 17,600 + 2,300 = 19,900 feet
Now the distance is left to reach the top = 29,135 - 19,900
= 9,235 feet
The climber is 9,145 feet farther to reach the top of the mountain.
(16). John Adams was born in 1732 and became president in 1797.
At that time his age was = 1797 - 1732 = 65 years
Harry S. Truman was born in 1884 and became president in 1945.
At that time his age was = 1945 - 1884 = 61 years
John Adams was older when he became president.
