we know that
The simple interest formula is equal to

where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have

substitute in the formula above

solve for r



therefore
<u>the answer is</u>
the rate of interest is 
First you would change the time from minutes to seconds by multiplying 4 by 60 because there are 60 seconds in a minute. After finding that (4*60=240) you would subtract the remaining time (12 seconds) from the total time (240 seconds). You would subtract the remaining time from the total time (228 seconds). Using that you would use the ratio time used/total (228/240). Divide that out and multiply by 100 to get 95%. I hope that helps!
