Question

Two cars are 100 miles apart. If they drive towards each other they will meet in 1 hour. If they drive in the same direction they will meet in 2 hours. Find their speed by using graphical method​

Answer 1

Answer:

Let x, y be the speed of the two cars. If the two cars travel towards each other they will meet in 1 hr. The distance between them d = 100; d s ds = t i.e., 100 x + y 100x+y = 1 ⇒ x + y = 100 … (1) If the two cars travel in the same direction they will meet in 2 hrs. x + y = 100 2 1002 ⇒ x – y = 50 … (2) Read more on Sarthaks.com - https://www.sarthaks.com/965736/cars-miles-apart-they-drive-towards-each-other-they-will-meet-hour-they-drive-same-direction?show=965788#a965788
