Suppose Juan can bike 6 miles in 10 minutes. If the rate remains constant, how many miles can he bike in 30 minutes?
-------
It's 3 times the time, so it's 3 times the distance.
3*6 = 18 miles in 30 minutes
=================
The lesson is, ignore irrelevant statements in a problem.
"At this rate he can bike 15 miles in 25 minutes."  does not matter.
