Given that 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.
Then speed of olympian = distance/ time = 100 meter/ 9.6 seconds = 100 meter/ 9.6 seconds = 10.4166666667 meter/ seconds
whis is approx 10.42 meter/seconds
Now we need to find about how much faster was Sarah the cheetah’s speed, to the nearest tenth of a meter per second.
16.8-10.42 = 6.38 = 6.4
Hence speed of Sarah the cheetah's is approx 6.4 meter per second more than the speed of olympian.
