Answer 1

In order to get the answer you'd have to double the fraction 18/25 to get 36/50
Then you would add 36/50 and 41/50
This would result in getting the fraction 77/50
That would simplify 1 27/50 miles

Answer 2

1 27/50 miles

18/25 multiply by 2 to get common denominator, then add 41/50 which gives you 77/50, then simplify.
