Voldemort has a savings account containing $\$10000$. Interest accumulates so that every five years, the amount of money in that account grows to 11/10  of its amount at the beginning of the five years. How much money is in that account after twenty years, given that no money is put into or taken out of the account?

 

We  have  4 compounding  periods  in a 20 year period.....so...

 

10000  (11/10)^4  =   $14,641

From  6 - 7   =  40 miles

From 7 - 8   =   20 miles

From 8 - 10  =  60 miles

From 10 - 11  = 40 miles

 

Avg  speed  =  Distance traveled  / Time  traveled =   [ 40 + 20 + 60 + 40 ]  / 5  = [ 160 ] / 5  =

 

32  mph
