Question

How can you use integers to represent the velocity and the speed of an object?

Answer 1

1)The SPEED of an object tells us how fast this object is moving, bit it doesn't indicate the direction of :
Speed = distance/time

2) The VELOVITY of an object tells us how fast this object is moving and in which direction it's moving ( If UP, then it's positive. If DOWN, then it's negative. Same logic for moving right (+) or left (opposite to right, then -) 
Velocity = distance/time

In short te absolute value of Velocity = Value of speed:

| Velocity | = Speed
