Question

A

Answer 1

Hello! For this excersice let's applicate the formula:

$\boxed{\boxed{d=vt}}$

Data:

d = Distance = 150 m

v = Velocity = ¿?

t = Time = 0,9 s

Now, let's replace according the formula:

$\boxed{150 \ m = v * 0,9 \ s}$

• Clear v:

$\boxed{\dfrac{150 \ m}{0,9 \ s} = v}$

• Resolving:

$\boxed{166,67 \ m/s = v}$

The velocity is 166,67 meters per second.
