Question

If a boat traveled 6n^2 + 4n miles at an average speed of 2n miles per hour, how long did it take the boat to travel the given distance?

Answer 1

Answer: 3n+2 hours

To get this answer, you divide the distance over speed

This is because

distance = rate*time

time = distance/rate

So we have

time = (distance)/(rate)

time = (6n^2+4n)/(2n)

time = (6n^2)/(2n) + (4n)/(2n)

time = 3n + 2 hours
