3. OLYMPICS Four runners are entered in the first hurdles heat of twelve heats at the
Olympics. The first two move on to the next round. Assuming no ties, how many
different ways can the four runners come in first and second place?

The solution to the system of equations (-2,2)

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
