Answer :
400 minutes x 5= 2000minutes
(2000minutes x 60)seconds =120,000seconds
(2000minutes x 60)seconds =120,000seconds
If a student is in class 400 minutes every day for 5 days each week, then there would be 120000 seconds, therefore the correct answer is option A.
What is multiplication?
Finding the product of two or more numbers in mathematics is done by multiplying the numbers. It is one of the fundamental operations in mathematics that we perform on a daily basis.
As given in the problem If a student is in class 400 minutes every day for 5 days each week,
The number of minutes a student in class in a day = 400 minutes
The number of seconds a student in class in a day = 400 × 60 seconds
The number of seconds a student in class in a week = 400 × 60 × 5 seconds
The number of seconds a student in class in a week = 120000 seconds
Thus, the correct answer is option A.
