Suppose you define a flight to be "on time" if it gets to the destination on time or earlier than expected, regardless of any departure delays. Mutate the data frame to create a new variable called `arr_type` with levels `"on time"` and `"delayed"` based on this definition. Then, determine the on time arrival percentage based on whether the flight departed on time or not. What proportion of flights that were `"delayed"` departing arrive `"on time"`?

(hint: you can test that this formula is working by changing the value in cell q2 to 0, but remember to set the value of cell q2 back to 1036 when the testing is complete.)
