Answer:

140 minutes or a little over 2 hours

Step-by-step explanation:

So if it took Rachel 15 minutes to grade 3 projects, that means it took 5 minutes to grade each one. 3x5=15

So going by if Rachel took the same amount of time to grade all 28 projects, each 5 minutes, it would be 28x5= 140 minutes
