Answer 1

Answer:

B

Step-by-step 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:

$\frac{\frac{1}{5}}{\frac{3}{4}}=\frac{x}{1}\\\frac{3}{4}x=\frac{1}{5}*1\\\frac{3}{4}x=\frac{1}{5}\\x=\frac{\frac{1}{5}}{\frac{3}{4}}\\x=\frac{1}{5}*\frac{4}{3}\\x=\frac{4}{15}$

B is the correct answer.
