Robert is running in a race that is 3 miles long. a distance marker is placed evenly every 1/2 mile from the beginning of the race until the end. what is the total number of distance markers on the trail?

the total number of distance markers on the trail is 6

Step-by-step explanation:

The total distance that Robert covers in the race is 3 miles.

If a distance marker is placed evenly every 1/2 mile from the beginning of the race until the end, then the total number of distance markers on the trail would be

3/0.5 = 6

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
