Sagot :
Answer:
It will take Marcus 56 minutes more to deliver 100 papers than 72 papers.
Step-by-step explanation:
Suppose Marcus delivers papers at a rate of 9 papers in 18 minutes.
So, he can deliver 100 papers in = [tex]\frac{18}{9}\times100= 200[/tex] minutes
He can deliver 72 papers in = [tex]\frac{18}{9}\times72= 144[/tex] minutes
Difference in delivering time = [tex]200-144= 56[/tex] minutes
Hence, it will take Marcus 56 minutes more to deliver 100 papers than 72 papers.
