Answer:
16.34 hours
Step-by-step explanation:
According to the given information we can see that the case is of exponential growth
Hence, we will use the formula
Here A =800 is the amount that is needed to reach
P is the initial amount that is 500
We have to find the time it will take to reach 800 that is we need to find t
On substituting the values in the formula we get
On simplification we get
Taking log on both sides we get
using
And
Now substituting values of log 8=0.903, log 5=0.698 and log 2=0.301 we get
