Answer:
Step-by-step explanation:
Let r represent Linda's walking rate.
We have been given that Linda can ride 9 mph faster than she can walk, so Linda's bike riding rate would be 
miles per hour.
We have been given that Linda can bicycle 48 miles in the same time as it takes her to walk 12 miles.
Since both times are equal, so we will get:
Therefore, the equation can be used to solve the rates for given problem.
Cross multiply:
Therefore, Linda's walking at a rate of 3 miles per hour.
Linda's bike riding rate would be 
miles per hour.
Therefore, Linda's riding the bike at a rate of 12 miles per hour.

( * = multiplication symbol, specifying as many feel confused )
A = l * w
Here..... A = 54 m², w = 9m
54 = l * 9 or...
9 * l = 54
