Answer by Okamiden(22)   (Show Source):
You can put this solution on YOUR website! We have this problem :
.
715 miles.....13 hours
605 miles.....? hours
.
We could wonder how many miles per hour Aldo does :
If Aldo does 715 miles in 13 hours, then in only one hour, Aldo will travel 13 times less far:
715 divided by 13 = 55 miles per 1 hour.
.
We now have this:
55 miles.....1 hour
605 miles....? hours
.
Here, we have that 605 divided by 55 = 11, so 605 miles is 11 times the distance of 55 miles. Thus, it will take 11 times as many hours to do 605 miles instead of 55 miles :
55 miles.....1 hour
605 miles....11 hours
Answer : 11 hours
