Dr. stein bought 30 notebooks, 60 pencils and 300 erasers to make identical packages with some notebooks, some pencils and some erasers for his students. he used everything he bought, and every student got a package. what is the largest number of students dr. stein can have in his class?

M.m.c (30, 60, 300)
30, 60, 300|3
10, 20, 100|2
 5, 10,   50 |5
 1,  2,    10 | ===> 3*2*5 = 30 
30 stundents

The key word is "identical." If all students received identical packages, then Dr. Stein could have handed out 30 packages. He has a maximum of 30 notebooks to hand out, so if each package has one notebook, he can hand out 30 packages. Each of those 30 packages will also have 2 pencils and 10 erasers.

ANSWER: There are 30 packages maximum so he can have a maximum of 30 students.

Hope this helps! :)

Step-by-step explanation:

The speed of the car is 100/5 = 20 m/sec (speed = distance/time)

 

1m/sec is 2.237 m/hr. Using the conversion factor the speed of the car is 44.74 miles/hr.
