# Distance covered by two object from different initial point

Two cars, an Edsel and a Studebaker, are 635 kilometers apart, with Edsel moving behind Studebaker(otherwise they won't never meet, by the speeds given). They start at the same time and drive in one direction . The Edsel travels at a rate of $$70$$ kilometers per hour and the Studebaker travels $$57$$ kilometers per hour. In how many hours will the two cars meet?

• how many km are removed from the remaining distance every hour ? then apply cross-muiltiplication.

• Divide the total distance traveled by the total distance the two cars travel in one hour. Commented Dec 2, 2018 at 11:55
• Depending upon what direction they are traveling they may not meet but in other direction they will meet. At that time what will the impact be? Commented Dec 3, 2018 at 0:30

Edsel will have to cover $$635$$ kilometers faster compared to Studebaker in order to meet him. Further, he's moving $$70-57=13$$ km/h faster than Studebaker. So, he'll meet Studebaker in: $$T=\frac{635\text{km}}{13\text{km/hr}}=\boxed{48.846\text{ hr}}$$
