So if he ran 100 meters in 12 seconds how many meters in 1 second?
OpenStudy (texaschic101):
do a little bit of dividing...
100/12 = what ?
75/8 = what ?
OpenStudy (amorfide):
use the equation
speed=distance/time
find out the speed for each person
OpenStudy (anonymous):
@texaschic101 8.3 and 9.375

Chris?
OpenStudy (texaschic101):
