Answer: 240.8 m/s & 8.669x10^8 km/hr
Explanation: a) V= [tex]\frac{602m}{2.50s}=240.8 m/s[/tex] or 2.408x10^2 m/s (when you divide, final units just become the top unit over the bottom unit)
b) V= [tex]\frac{602m}{2.50s}X\frac{3600s}{1hr}X\frac{1000km}{1m}=8.669X10^8[/tex]
(each unit cancels so the first seconds cancel and turn into hours and then the meters cancel and turn into km)
