Question 844892: A car passes a landmark on a highway traveling at a constant rate of
50
kilometers per hour. One hour later, a second car passes the same landmark traveling in the same direction at
70
kilometers per hour. How much time after the second car passes the landmark will it overtake the first car?
Do not do any rounding.

You can put this solution on YOUR website! The landmark could as well be a departure point from which the two cars leave at different times each at its own given speed, in the same direction.
Travel uniform rate equation R*T=D, for rate time distance;
let t = the time for the late, faster car, to catch-up to the earlier car
________________speed________time_________distance
Early car_______50___________t+1__________50(t+1)
Late car________70___________t____________70t
Can you figure what do do next?
