Based on the time that Rex walked and the time that Samir walked, we can say that Samir walked TWO times as many hours as Rex walked.​
To find out how many times more Samir walked than Rex, divide the number of hours walked by Samir by the hours walked by Rex.
Solving gives:
= 3¹/₃ ÷ 1²/₃
= 10/ 3 ÷ 5/3
= 10/3 x 3/5
= 30/ 15
= 2 times more
In conclusion, Samir walked two times more.
