Answer 1

B

Explanation:

1/5th the distance is 3/4th hour

We can setup a ratio that gives distance on top and hours on bottom. We can then equate that will what we want (the distance (let it be x) in 1 hour).

Hence,

the fraction on the left side would be 1/5 OVER 3/4 (distance/hours)

the fraction on the right side would be x OVER 1 (we want distance traveled in 1 hour)

Lets do this and cross multiply and find x:

`((1)/(5))/((3)/(4))=(x)/(1)\\(3)/(4)x=(1)/(5)*1\\(3)/(4)x=(1)/(5)\\x=((1)/(5))/((3)/(4))\\x=(1)/(5)*(4)/(3)\\x=(4)/(15)`

B is the correct answer.
