OBJECTIVE : Determine the distance travelled over a period of time (speed) of an object

[tex]{ \tt{FORMULA : s = \frac{d}{t} }}[/tex]

1. Distance = 624 kilometers; Time = 12 hours Speed = 54 km/hr

[tex]{ \sf{s = \frac{624km}{12hr} }}[/tex]

[tex]{\boxed{\sf{s = 52 km/hr}}}[/tex]

2. Distance = 864 meters; Time = 32 seconds

Speed = 27 m/s

[tex]{ \sf{s = \frac{864m}{32s} }}[/tex]

[tex]{\boxed{\sf{s = 27m/s}}}[/tex]

3. Distance = 972 miles; Time = 27 hours

Speed = 36 mi/s

[tex]{ \sf{s = \frac{972mi}{27hr} }}[/tex]

[tex]{\boxed{\sf{s = 36mi/s}}}[/tex]

4. Distance = 714 kilometers; Time = 14 hours

Speed = 51 km/hr

[tex]{ \sf{s = \frac{714km}{14hr} }}[/tex]

[tex]{\boxed{\sf{s = 51km/hr}}}[/tex]

5. Distance = 1125 kilometers; Time = 25 hours Speed = 45 km/hr

[tex]{ \sf{s = \frac{1125km}{25hr} }}[/tex]

[tex]{\boxed{\sf{s = 45km/hr}}}[/tex]
