Joe traveled from Austin to Leander last week. Joe completed 4/5 of the distance in the morning and 1/5 of the remaining distance in the afternoon. I still had 12 miles to travel. What is the distance from Austin to Leander?

What does this mean? " I still had 12 miles to travel" ??!!

x = total distance

x - 4/5x - 1/5 (1/5x) = 12

x = 75 miles
