Sandra runs at a rate of 8 miles in 45 minutes. How does her unit rate compare to Terrances and Jesse’s? (Terrence runs 6 miles every half hour, Jesse runs 2 miles every 15 mins)

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.

Hope this helps! :)
