speed = distance/time = 100mi/2h = 50mi/h
To calculate the velocity of the train, divide the distance traveled by the time taken. In this case, the train travels 140 miles in 2 hours, so the velocity is 140 miles / 2 hours = 70 miles per hour. Therefore, the velocity of the train is 70 mph.
The velocity of the train can be calculated by dividing the distance traveled by the time taken. In this case, the train travels 100 miles north in 2 hours, so the velocity is 100 miles / 2 hours = 50 miles per hour. Therefore, the train's velocity is 50 miles per hour to the north.
1600 / 80 = 20 hours by train 1600 / 200 = 8 hours by plane it will take 20 - 8 = 12 hours more by train
140 miles
Slow train takes 4 hours to do the 60 miles to Chicago. Fast train takes 2 hours to do the 60 miles to Chicago. 60 miles in one hour is 60 mph So 60 miles in two hours is 30 mph; that's the express. And 60 miles in four hours is 15 mph; that's the slow train.
1.4:1 in favor of the train.

805 miles divided by 7 hours is 115 miles per hour.
Divide 496 by 8. That will give you the speed in miles per hour.
80 miles per hour. All you have to do is divide 200 by 2.5.
