Answer:
The Martinez family walked three over five of a mile in three over eight of an hour. What equation can be used to calculate their unit rate in miles per hour?
three-fifths over three-eights equals one and three-fifths miles per hour
three-eighths over three-fifths equals one and three-fifths miles per hour
three-eighths over three-fifths equals five over eight mile per hour
three-fifths over three-eights equals five over eight mile per h
The correct option is three-eighths over three-fifths equals five over eight miles per hour.
Given: The Martinez family walked 3/5 of a mile in 3/5 of an hour.
To Find:- The unit rate in miles per hour.
Solution: We have,
The distance covered by the Martinez family= 3/5 of a mile
The time taken by the Martinez family=3/5 of an hour.
Therefore, as per the formula,
Distance/Time=Speed
Therefore, by putting the values we get,
3/8(miles)/3/5(hours)
=3/8*5/3
=15/24
=5/8miles/hour
Answer:- The walking speed of the Martinez family is 5/8miles/hour.
