100 sandwiches in 5 hrs so 100 sandwiches in 300 minutes
so each sandwich is 3 minutes. 3 times 12 sanwiches is 36 minutes.
You are correct.

he makes 100 in 300 minutes, so makes 1 sandwich every 3 minutes.
Therefore to make 12; 12 x 3 = 36 minutes.

Tom makes (100/5) or 20 sandwiches per hour. This means he takes an average of (60/20) or 3 minutes each. You can take it from there.

Yup. It is 36.
1/3 of a sandwich in a minute.
Divide 12 by 1/3.
12 times 3 is 36 minutes.
