Answer:
8 minutes per mile
Step-by-step explanation:
Geri ran in a marathon race.
It took her 3 hours and 28 minutes to run 26 miles.
1 hour = 60 minutes
we will convert the time into minutes
3 hour 28 minutes = (3 × 60) + 28
= 180 + 28
= 208 minutes
∵ Geri ran 26 miles in 208 minutes
∴ She ran 1 miles =
= 8 minute
Geri ran 1 mile in 8 minute.

Answer:
The correct answer is v(t) = (principal × time × 0.02) if calculated simply and v(t) = Principal × where v(t) is the interest after t years .
Step-by-step explanation:
Principal amount invested by Shota is $2000.
Interest is earned at 2% per year.
Time for which the principal is invested is t years.
Therefore let the total interest be v(t) dollars in t years.
Case 1: Simple Interest.
v(t) = (principal × time × ) = (2000 × t × 0.02) = 40t
Case 2: Compound Interest.
v(t) = Principal × - Principal = 2000 ×
- 2000.
