Answer:

40 minutes

Step-by-step explanation:

We can solve this problem through finding the proportion...

Let the time taken to travel 8 inches at the speed be x

Hence, 12:60 :: 8:x

We must multiply the extremes and the nears..

Hence,

12x=60×8

x=60×8/12

Answer: It will take $\frac{7}{3}$ of an hour to complete the test.

Step-by-step explanation:

We need to convert the mixed number $1\ \frac{1}{3}$ to an improper fraction:

$1\ \frac{1}{3}=\frac{(1*3)+1}{3}= \frac{4}{3}$

Now, we need to make the following add the fractions in order to calculate how many hours will it take to complete the test. Then, we get:

$\frac{4}{3}+\frac{1}{3}+\frac{2}{3}=\frac{4+1+2}{3}=\frac{7}{3}$

Therefore, it will take $\frac{7}{3}$ of an hour to complete the test.
