To find out how much longer he took on his return journey, we need to subtract the time it took for his initial journey from the time it took for his return journey.
First, let's convert 25 5/8 min to an improper fraction:
25 5/8 = 25 + 5/8 = 25(8/8) + 5/8 = 200/8 + 5/8 = 205/8
Now we can subtract the time for the initial journey from the time for the return journey:
205/8 - 18 = (205 - 8*18)/8 = (205 - 144)/8 = 61/8
Therefore, he took 61/8 min longer on his return journey.
A man took 18 min to row from one island to another. His return journey took 25 5/8 min. How much longer did he take to row on his return journey?
