Answer:
v = 1 i ^ m / s, v = 1 m / s
Explanation:
In this problem we show the difference between vectors and scalars.
The average speed is
v = Δx / Δt
The bold are vectors
Δx = 20-10 = 10 i^ m
v = 10/10
v = 1 i ^ m / s
the unit vector indicates that the velocity is on the x-axis
The average speed is
v =Δx / Δt
v = 10/10
v = 1 m / s
in this case we have a scalar
