John's velocity is 20 m/s north.
Betty's velocity is 20 m/s south.
Their speeds are both 20 m/s.
Answer:
Explanation:
Here we have to consider the gradient of the graph.
Gradient = ( Distance / Time ) = Speed
For
(a) Gradient is zero there fore straight line
(b) For uniform speed ( Constant speed ) gradient is constant .
(c) For none uniform motion gradient is not constant

Interesting . . . the largest planet rotates the fastest.
I wonder why that is.
Metallic bonding accounts<span> for many physical </span>properties of metals, such as strength, ductility, thermal and electrical resistivity and conductivity, opacity, and luster. I hope my answer has come to your help. God bless and have a nice day ahead!
