Please help me BIG POINTS

32minutes

Step-by-step explanation:

time for 150 people=20 min

time taken for 1 person =20÷150

time taken for 240 people=20÷150×240

=32

hope this helps

plz mark me brainliest

Step-by-step explanation:

Step 1:  Make an equation

Step 2:  Cross multiply

Step 3:  Divide both sides by 150

Option C, 32 min

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
