Answer:

60mph

Step-by-step explanation:

Speed is the rate of change in distance. Mathematically,

Speed = Distance/Time

Difference in distance between A and B = 285-105miles = 180miles

Total time taken between 2pm and 5pm is 3hours

Speed = 180miles/3hours

Speed = 60miles/hour

Therefore the train speed between the checkpoints is 60miles/hour
