We know that a train travels a distance of 34 miles in a time of 20 minutes, and from this, we want to find the speed of the train.
We can conclude that the train was travelling at 102 miles per hour.
To solve this, we need to remember the relation:
speed = distance/time
Here we know:
distance = 34mi
time = 20 minutes
But we want the speed in miles per hour, so we need to change the units of the time.
Remember that 1 hour = 60minutes, then:
20 minutes = (20/60) hours = (1/3) hours.
Then we have:
time = (1/3) hours.
Then the speed can be written as:
speed = 34mi/( (1/3) h) = (34*3) mi/h = 102 mi/h
We can conclude that the train was travelling at 102 miles per hour.
