Answer:



Step-by-step explanation:
Let
denote the half life of our substance
to be our time,
is mass at time t and
as initial mass. Our half life equation can be expressed as:
from which we can obtained mass at any given time.
b. From our equation above,
we can convert our t into mins as 
We then substitute
value into the equation

Hence mass after 4hrs is 
c. We can set our final mass to
then substitute in the equation
. Substitute 


Hence time until
mass is 109.83 minutes
9.4 is the distance coming back with pythagorean theorem
add the original 13 miles
22.4 miles
