Jane is walking her dog, spot. She sees her friend, Richard, walking toward her along the same long, straight road. Both Richard and Jane are walking at 3 mph. When Richard and Jane are 600 feet apart, Spot runs from Richard to Jane, turns and runs back to Richard, and then back and forth between them at a constant speed of 8 mph. Richard and Jane both continue walking toward each other at a constant 3 mph. Neglecting the time lost each time Spot reverses direction, how far has Spot run in the time it takes Richard and Jane to meet?

idk what the answer is but for the points

step-by-step explanation:

the first one and the second one that's the answer

2

step-by-2step explanation:

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
