Hi! I was doing quadratic and exponential word problems on Khan Academy, and got this. Is it possible that this type of problem will be on the SAT, and if it is, please explain it.
Question(reworded): A guy travels up a river at v mph for 2 miles. He goes the same distance back, but 5 mph slower than he did on the way up. If he spent 3 hours traveling up and back, which could be used to determine his speed on the way up the river?
