Answer using a coordinate system where rightward is positive. Round the answer to two significant digits.

-32 m/s

Step-by-step explanation:

Lebron bikes 800 m to the left in 25 seconds.

We are using a coordinate system where rightward is positive.

This means he is moving in the negative axis.

Hence, his displacement is actually - 800m.

Velocity is the displacement moved by an object divided by the time spent i. e.

v = d / t

His velocity is therefore:

v = - 800 / 25 = - 32 m/s

His velocity is - 32 m/s.
