Addie walked 2 1/2 miles in 45 minutes. suzie covered 2 2/5 miles in 2/3 of an hour.
what was suzie's speed? (i need this now! first to answer gets 5 stars and a , and if possible the brainliest answer! )

Suzie's speed was 3.6 mph

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

s ----> the speed in mph (miles per hour)

x ----> the distance in miles

y ----> the time in hours

so

Find Suzie's speed

we have

substitute

Convert mixed number to an improper fraction

substitute

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

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
