train A leaves a station at 1:15 PM,traveling 60 mph.Train B leaves the same station, in the same direction as train A,15 minutes later.If train B travels 90mphm when (clock time)will train B catch up to train A and how far down the track does this occur?

try to set up an equation im in algebra 2 so i may be able to help you

A train leaves the station and travels north at 85 km/hr. For hour later, a second train leaves on a parallel track and travels north at 125km/hr. How far from the station will they meet?

To determine when and where train B catches up to train A, we need to find the time it takes for train B to catch up and the distance traveled by both trains during that time.

Let's start by finding the time it takes for train B to catch up to train A.

Train A leaves the station at 1:15 PM, while train B leaves 15 minutes later. This means that train B starts its journey at 1:15 PM + 0 hours and 15 minutes = 1:30 PM.

Now, we need to find the time it takes for train B to catch up. To do this, we compare the relative speeds of the two trains.

Train A is moving at a speed of 60 mph, while train B is moving at a speed of 90 mph. The speed difference between the two trains is 90 mph - 60 mph = 30 mph.

Since train B is traveling faster than train A, it will catch up at a rate of 30 miles every hour.

To determine the catching up time, we divide the distance between the two trains at the time of train B's departure (15 minutes later) by the rate at which train B catches up. The relative distance between the two trains is 0 miles at this point.

Catching up time = Distance / Relative Speed
Catching up time = 0 miles / 30 mph = 0.

Therefore, it will take train B 0 hours to catch up to train A.

Next, let's determine how far down the track this occurs.

Since train B catches up to train A at a relative distance of 0 miles, this means the two trains will meet at the same point on the track.

So, train B catches up to train A at the same distance from the starting point.

Therefore, train B catches up to train A right at the station where they both initially departed.

In summary, train B catches up to train A at 1:30 PM, right at the station where they both departed.
