Question 891415
t = the amount of time each driver drove
d = amount of distance Paul drove
RT=D for rate time distance, the uniform rates travel equation in general.



________________speed_______time_______distance
Peter____________70__________t___________d-30
Paul_____________75__________t___________d


Form the two obvious equation in the two unknown variables and solve the system.

JUST A LITTLE MORE....


Using the uniform rates equation RT=D, rate time distance, as a fundamental model, form the equations:
{{{70t=d-30}}} and {{{75t=d}}}.
SOLVE THIS SYSTEM.
