Questiom and answer
As the time graph
Juliet is the fastest.Because in the same distance,she uses the least time
The Vave of Juliet is about 13.7 m/s
The Vave of Jenny is about 5.3m/s
The Vave of Carrie is about 7.55m/s
The Vave of Lois is about 6.67m/s(During the 10s~30s)
The same as above.
They are changing.Because as the time graph shows,they are not straight lines.
The Vave of Juliet is about 7.20m/s(during 0s~80s)
The Vave of Carrie is about 6.02m/s(during 0s~60s)
The speed is equal to distance over time.So we can get them.
The Vave of Jenny is about 5.63m/s
The Vave of Juliet is about 7.21m/s
The Vave of Lois is about 5.64m/s
The Vave of Carrie is about 6.20m/s
10.NO.WE cannot have the same speed at each time.
