You can put this solution on YOUR website! A car passes a landmark on a highway traveling at a constant rate of 55 kilometers per hour.
One hour later, a second car passes the same landmark traveling in the same direction at 63 kilometers per hour.
How much time after the second car passes the landmark will it over take the 1st car?
:
One hour later the first car will be 55 mi from the 2nd car passing the marker.
let t = time required for the 2nd car to overtake the 1st car
When this happens, they each will have traveled the same distance
Write a distance equation
63t = 55t + 55
63t - 55t = 55
8t = 55
t = 55/8
t = 6.875 hrs or 6hrs + .875(60) = 52.5 min
