A dog won a race at the local fair by running 3 and one fourth miles in exactly 2 hours. At this constant rate, how long does it take the same dog to run the 1 and three tenths -mile state fair race? Use ratio reasoning to solve.

hour

Step-by-step explanation:

Let x represent time taken by dog to run the 1 and three tenths -mile state fair race.

We have been given that a dog won a race at the local fair by running 3 and one fourth miles in exactly 2 hours.

We will use proportions to solve our given problem as:

We will equate both speeds as:

Cross multiply:

Therefore, it will take hour to complete mile state fair race.

answer:   (s+1)(s+4)

step-by-step explanation:

factor s2+5s+4

s2+5s+4

=(s+1)(s+4)

answer: (1,3) (3,-1) (5,-5) ?
