Step-by-step explanation:

Note: When a body is travelling at uniform acceleration, the average velocity is given as  

Given

initial velocity u= 3 m/s

final velocity v= 5 m/s

To express this in mixed number we have

$54.99

step-by-step explanation:

$54.99 includes 500 min. if she does not exceed 500 min then her bill is $54.99
