A= there are "4"one fourths in one hour and he hikes 2 miles every hour
B= 1, 1 1/2, 2, 4
C= it going to be 1/3 mile for every 1/6hour and she hikes 2 miles every hour.
D= 2/3, 1, 2, 4
Answer:

Step-by-step explanation:
10 * sqrt(81/25 * -1) = 10 sqrt(81/25) * sqrt(-1) = 10 *9/5 * i
We must find time by using the simple interest formula:
I = P x i x t
I is the interest
P is the total principal
i is the rate of interest per year
t is the total time in years
In this example, when we plug our known values in, our formula looks like this:
t =

t =

t = 4
So time (in years) would be 4 years.
The last one
