very got on the bus at 4:20 P. M. The trip took 80 minutes. Then she walked for 49 minutes to get home. At what time did Avery arrive at home?

6:29pm

Step-by-step explanation:

there 60min in a hour and that's what I got

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
