75 miles per hour can be covered.
2.58 miles / 61 minutes * 60 minutes/hour ~= 2.538 mph
37mph. 18.5 miles in half an hour X (2) twice as long means you could've covered 37miles in one hour... aka 37MPH
The distance covered in 1 hour and 20 minutes would depend on the speed at which you are traveling. If you are traveling at a constant speed of 60 miles per hour, then in 1 hour and 20 minutes (or 1.33 hours), you would cover 80 miles (60 miles/hour * 1.33 hours). However, if you are traveling at a different speed, you would cover a different distance. To calculate the distance covered, you would multiply the speed (in miles per hour) by the time traveled (in hours).
Assuming a constant average speed of 50 miles per hour, 891 miles will be covered in 891/50 = 17.82 hours or 17 hours 49 minutes 12 seconds.
12.43 miles.
If you're saying that it takes 2 minutes 30 seconds to cover 1 mile, then the number of miles covered in 1 hour is 60/2.5 = 24 miles.
4 minutes is 1/15 of an hour. In one hour, the train would travel 30 miles. Multiply that by 1/15 to get 2 miles in 4 minutes.
