Answer:
3 question papers
Step-by-step explanation:
If the teacher takes 15 minutes to mark 1 question paper. Then they will probably take 30 minutes to grade 2 question paper. Because 15 minutes+15 minutes=30 minutes. Then if you and another 15 minutes which will be 40 minutes because 15 minutes+15 minutes+15 minutes=40 minutes.
Hence, the teacher will mark 3 question papers in 40 minutes
55 times 30 is 1650 and 30 times 5 is 150
The answer is 1650 over 150
A/b=c
times both sides by b
A=bc
divide both sides by c
A/c=b
b=A/c
