Answer:
The hikers A and B travel at rates of 1.1 miles per hour and 3.3 miles per hour, respectively.
Step-by-step explanation:
Let suppose that each hiker travels at constant speed, such that kinematic formulas are, respectively:
Hiker A
Hiker B
Relationship
(They walk toward each other)
Where:
,
- Initial and final position of the hiker A, measured in miles.
,
- Initial and final position of the hiker B, measured in miles.
- Time, measured in hours.
,
- Velocities of hikers A and B, measured in miles per hour.
Given that ,
,
and
, the system of equation is reduced to the following:
Now, the velocity of the hiker A is:
The hikers A and B travel at rates of 1.1 miles per hour and 3.3 miles per hour, respectively.
Answer:
years = natural log (total / principal) / rate
years = natural log (18,400 / 9,200) / 10
years = natural log (2) / 10
years = 0.69314718056 / 10
years = 6.9314718056
