Factors that contribute to income inequality are closely linked to economic, social and political causes. People have different wages for each job, leading to income inequality. People of different levels of education often earn different wages, but their social situation can be different as they grow up.

Explanation

 7t

First person distance traveled in time t = 28

 laps = 1

4 laps 

 Distance covered by the second person at time t = 38

 laps 

 First-person speed = 14t

 Second-person speed = 38t

 The two  start from A and B respectively, so they  meet  when there is a difference of 78

 laps. 

 Relative velocity of A and B: 

 = (38t-14t) = 18t

 Time  to complete 78

 laps at this speed: 

 = (78 × 8t) = 7t
