Question

If it takes a fan 20 minutes to walk to her seat in the last section in the stadium and it takes 5 minutes to get to the lowest-level seats, what is the average time to find a seat in these two sections at the stadium?

Answer 1

The last section in the stadium
 t1 = 20min
 the lowest-level
 t2 = 5min
 The average between those two sections of the stadium to find a seat is:
 A = (t1 + t2) / (2)
 A = ((20) + (5)) / (2)
 A = (25) / (2)
 A = 12.5min
 Answer:
 The average time to find a seat in these two sections at the stadium is
 12.5min
