Driving from Cleveland to Washington, D.C., Ernie averaged $60$ mph for the first $2$ hours, $20$ mph the next hour due to construction, and $65$ mph for the final $3$ hours of his journey.

1. How fast was Ernie going after one hour?

   Hint (a):

   Ernie averaged $60$ mph for the first $2$ hours. Does this mean he drove at a constant rate?

2. What was Ernie’s average rate for his entire $6$-hour trip?

   Hint (b):

   average speed $=$ total distance / total time
   
   Determine Ernie's total distance from the given information.
   Then divide by the total time ($6$ hours).
