Answer:
Unit rate by which the runner completed the marathon is 0.13 miles per minute.
Step-by-step explanation:
A runner competed a marathon of 26.2 miles in 210 minutes.
we can get unit rate by unitary method.
∵ In 210 minutes a runner completes the distance = 26.2 miles
∴ In 1 minute runner will complete the distance = 
= 0.125 miles per minute
≈ 0.13 miles per minute
Therefore, unit rate by which the runner completed the marathon is 0.13 miles per minute.
The future worth of a certain item or money deposited at a certain percentage is obtained by the equation,
F = P x (1 + i)^n
F is the future worth, P is present worth, i is the percentage, and n is the number of years.
n = 2013 - 1938
n = 75
Substituting the known values,
300,000 = 100 x (1 + i)^75
The value of i from the equation is 0.1126.
The answer to this item is 11.26%.
