Problema Solution
Two trains are 600 miles apart, and their speeds differ by 20 miles per hour.find the speed of each train if they are traveling toward each other and will meet in three hours.
Answer provided by our tutors
Let one speed = x
So second = x+20
So relative velocity = 2x+20
So time taken = 600/(2x+20)= 3
or 6x+60=600
or 6x=540
or x= 90 km/s
So the other speed = 110 km/s
