Train A is going 60 miles per hour

Train B is going 70 miles per hour

Let rA = x, then rB = x + 10, and t = 3, then

trA + trB = 390

3x + 3(x + 10) = 390

3x + 3x + 30 = 390

6x = 360

x = 60

x + 10 = 60 + 10 = 70

Wo trains leave the station at the same time going in opposite directions One of the trains travels at 90 mph and the other is traveling at 120 mph After how many hours will they be 735 miles apart?

Going in opposite directions, they separate at the rate of (90 + 120) = 210 miles per hour.They are 735 miles apart after (735/210) = 3.5 hours.


If two trains on the equator start at the same point but facing in opposite directions which train will reach the point where it started first?

Both trains will reach the starting point at the same time since they are moving in opposite directions on the equator, which forms a complete loop. The distance traveled by both trains will be the same, so they will meet at the starting point simultaneously.

How do trains poerate?

Trains are mounted onto tracks on the rail road that steer them towards the pre-set directions they are meant to travel towards. Rail engineers then control the speed the train travels at, and when they should stop.

Theres two trains leaving at the same time one going 60 miles per hour one going 50 miles per hour in 90 minutes how far apart will they be?

The distance travelled by each train is equal to its speed in miles per hour multiplied by the time travelled in hours. Since there are 60 minutes per hour, 90 minutes = 90/60 = 1.5 hours. Since no directions are given, presumably the trains are traveling in the same direction or in opposite directions. The distance between the trains will be 1.5(60 - 50) if the trains are traveling in the same direction and 1.5(60 + 50) if the trains are traveling in opposite directions. These values are 15 miles and 165 miles respectively.
