Marneshia walked three over eight of a mile in three over five of an hour. What equation can be used to calculate her unit rate in miles per hour?

a three eighths over three fifths = five eighths mile per hour
b three eighths over three fifths = one and three fifths miles per hour
c three fifths over three eights = one and three fifths miles per hour
d three fifths over three eights = five eighths mile per hour

Answer 1

The Answer is A

Explanation:

First you take 3/8 and 3/5. After that, you put 3/8 over 3/5. To get Miles per Hour, you want to put distance over time. Next you invert and multiply. When you are doing this you want to have it looking like this:
`(3)/(8)` *
`(5)/(3)`. Finally you multiply the top and the bottom and reduce the fraction. Your final answer will me 5/8.
