Eitan is on a train heading west into the city while Dmitri is on a train on the adjacent track heading east, away from the city. They start 150 miles apart. Eitan’s train is traveling at an average speed of 65 miles per hour while the average speed of Dmitri's train is 55 miles per hour. How long will it take the two trains to reach each other? How far outside the city will they be?

The time when the two trains reach each other is ________.

The trains are _________ away from the city when they reach each other.

1 answer

The time it will take for the two trains to reach each other can be calculated using the formula: Time = Distance / Relative Speed

The total distance that needs to be covered by the two trains is 150 miles. The relative speed at which they are approaching each other is the sum of their speeds: 65 mph + 55 mph = 120 mph.

Therefore, the time it will take for the two trains to reach each other is 150 miles / 120 mph = 1.25 hours.

When the two trains reach each other, they will be 75 miles away from the city in each direction.
