We have a number .
To write it as a fraction first count the number of decimals and call it (which, in our case, has a value of 3). Multiply the number with
to get
. Then divide this number by
to get
from here you can either simplify (if the assignment says so, then the simplified fraction is
) or not.
Hope this helps.
Answer:
Therefore Josie drove 57.5 miles.
Step-by-step explanation:
Speed: The ratio of distance to time.
To find the distance we use the following formula
Given that Josie drove 45 minutes at 70 miles per hour.
In 45 minutes, she traveled =
