Answer:
First term of the sequence is 
Step-by-step explanation:
Let 
be the first term and 
be the common difference
We have
The sum of the second term and the ninth term of an arithmetic sequence is 
The sum of the third and fourth terms of the same sequence is 
eqn 1 - eq2
Substituting in eqn 1
First term of the sequence is
We will use the equation:
r t = 3/4 r ( t+12 ) /:r
t = 3/4 t + 9
t - 3/4 t = 9
1/4 t = 9
t = 9 * 4 = 36 minutes ( takes a trip to the market )
36 + 12 = 48 minutes
The ride home takes 48 minutes.
