Answer:
22.31 minutes
Explanation:
First simplify the numbers to decimals to make it easy : 2 1/3 = 2.30( estimated) , 11 2/3 = 11.67 ( estimated ), and 4 2/5 = 4.4
The we divide how many miles by the total amount of minutes to get 5.07( estimated )
We then multiply it by 4.4 to get 22.308 to be exact.
So it will take him 22.31 minutes
