Sarah the cheetah ran 100 meters at a speed of 16.8 meters per second. an olympian ran the 100-meter dash in 9.6 seconds. how much faster was sarah the cheetah’s speed, to the nearest tenth of a meter per second? 0.9 meters per second 1.6 meters per second 6.4 meters per second 10.4 meters per second

First let us calculate for the speed of the Olympian runner by taking the ratio of distance over time.

Olympian speed = 100 m / 9.6 s

Olympian speed = 10.4 m/s

Therefore the difference in speed is:

16.8 m/s – 10.4 m/s = 6.4 meters per second

6.4 meters per second

Step-by-step explanation:

Sarah's speed, to the tenth of a meter per second, is 16.8.

The Olympian ran 100 meters in 9.6 seconds; this speed is given by

100/9.6 ≈ 10.4

This makes Sarah's speed faster by

16.8-10.4 = 6.4 meters per second

the correct answer is b.

this is because an open circle means < or > & since the line goes left it is < -3.

the next one has a filled circle so it can only be ≥ or ≤ and since the line goes right from 1 it is ≥ 1
