1. Kank the runners from 1 place to 5" place.
2 Why did you consider the runner as rank 17. rank 57
Il you have answered runner C as rank 1, runner A as rank 2. runner B as
rank 1, runner D as rank 4 and runner E as rank 5 then you are correct. At the
same distance travelled runner C ia the fastest because he has the shortest time
and ranner E is the slowest because he has the longest time of travel. How do you
determine how fast the body or object has travelled?
Speed is defined as how fast an object is moving. Itis operatio
as distance divided by time. To calculate how fast an object ia movir
below is used.

where v-speed
d- distanee
t- time
The units of speed can be meter per second (m/s), kilometer per hour
(km/hr or kph), miles per hour (mi/hr or mph) and others
Velucity is the rate at which an object changes its positinn. To calculate the
velocity the equation helow is used
