It is actually quite simple just do 400/36=11.111111... and simplify.

You can also rule out A and B because they round to 100th not 10th

The correct option is 11.1 meters per second.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

Since:

Speed = Distance /time

We simply have to divide the distance (400) by the time (36) to calculate the speed.

Mathematically speaking:

Speed = 400 meters / 36 seconds= 11.1 m/sec

The correct option is 11.1 meters per second.
