the train travels 115 miles in 65 minutes.

it makes 3 stops with an average of 2 minutes apiece.

the total time stopped is therefore 6 minutes.

this means that its travel time was 59 minutes.

it's speed is therefore 115 / 59 = 1.949152542 miles per minute.

multiply that by 60 and you get 116.9491525 miles per hour.
