Answer:
1 3/8 miles per hour
Step-by-step explanation:
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?
3/5mile = 3/8 hour
Their unit rate in miles per hour or speed
= Distance/Time
Hence,
3/5mile ÷ 3/8 hour
= 3/5 × 8/3
= 8/5 miles per hour
= 1 3/8 miles per hour
Therefore, their unit rate in miles per hour is 1 3/8 miles per hour.
