ASAP math word problem please help: A plane traveling with the wind travels 900 miles in 5 hours. The return trip is against the wind and takes 9 hours. Find the rate of the plane in still air and the rate of the wind

the correct answer is 45x

9×5=45 then add the x

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

b). 4320 have a nice day
