One week a student exercised 2 hours at school and 2/3 hour at home. If 1/4 of the student's total exercise came from playing basketball, how much time did the student spend playing basketball that week?

The student played basketball for 40 minutes.

Step-by-step explanation:

Given that one week a student exercised for 2 hours at school and for 2/3 of an hour at home, it can be stated that the student exercised for 2 hours and 40 minutes (since 60 x 2/3 is equal to 40 ). Thus, in total the boy exercised for 160 minutes (2 x 60 + 40).

Now, since he spent 1/4 of that time playing basketball, the time spent doing this sport is determined through the following calculation:

160/4 = X

40 = X

Thus, the student played basketball for 40 minutes.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
