Answer:
Her unit rate is less than that of Terrance but more than that of Jesse.
Step-by-step explanation:
Since,
For sandra,
Distance = 8 miles, time = 45 minutes = = 0.75 hours,
( ∵ 1 hour = 60 minutes )
Thus, the unit rate of Sandra =
For Terrance,
Distance = 6 miles, time = hour = 0.5 hour,
Thus, the unit rate of Terrance =
For Jesse,
Distance = 2 miles, time = 15 minutes = hour = 0.25 hour,
Thus, the unit rate of Jesse =
Hence, Sandra's unit rate is less than that of Terrance but more than that of Jesse.
