Adonkey walked down a path along thegrand canyon his speed was 10 miles a hour the path length is 25 miles how long will it take him to reach the end of the path? ?

The correct answer is 2.5 hours.

Step-by-step explanation:

If the donkey is walking 10 miles per hour, in 2 hours he will each the 20 mile mark. In .5 of an hour he will go 5 miles. 25 miles total would be 2.5 hours.

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
