Ryan's mother measures his height and records in a notebook how much he has grown each year. Here is his growth data for the last five years: $2\frac{1}{4}$inches, $4$ inches, $2\frac{1}{2}$inches,  $3\frac{3}{4}$inches, and $3\frac{1}{2}$inches.

1. How much has he grown in the last five years?

   Hint (a):

   This problem is very similar to problem 3-85, where Jollie's mother kept a growth chart of her.
   Look back at problem 3-85 part (a) to help you solve this problem.

2. If Ryan was $4$ feet, $6$ inches tall when his mother started measuring him five years ago, how tall is he now? Give his height in feet and inches.

   Hint (b):

   Three years ago, Ellen was $4$ feet tall. In the past three years, she has grown 14 inches.
   That means she is now $5$ feet, $2$ inches tall, since $4$ feet $+$ $14$ inches $=$ $5$ feet, $2$ inches.
   
   Use the above example to help solve the problem about Ryan.

   More Help (b):

   It might be easiest to change all measurements to inches before adding them.
   Just remember to change them back to feet at the end.
