You can find a "literal solution" using t or x as the time the faster student took.
But, it's not spec'd that they started at the same time, so that's meaningless.
-----
If it said: "A student can finish a project in 15 minutes less than the other student ..." that would at least make sense.
-----
Then, "How long will it take ..."
It will take zero (0), since they're already finished it.
