40 miles/hr = 40*5280/60 = 3520 ft/min = 70.4 cars/min
140.8 cars pass in two minutes.
140.8 cars pass in two minutes.
40 / 60 * 2 = 1.333 Miles.
There are 5280 feet in one mile, so that would make the train:
5280 * 1.334 = 7040 feet long
The cars are 50 feet long each, so that would make the train have:
7040 / 50 = 140.8 Cars Long.
First, let's convert the train speed from miles per hour (mph) to feet per minute (ft/min) since the length of each car is given in feet.
1 mile = 5280 feet
1 hour = 60 minutes
Therefore, the train speed in feet per minute can be calculated as follows:
Speed = (40 miles/hour) x (5280 feet/mile) / (60 minutes/hour)
= 3520 feet/minute
Given that the entire train takes 2 minutes to pass a station and the speed is 3520 feet/minute, we can calculate the total distance traveled by the train.
Distance = Speed × Time
= 3520 feet/minute × 2 minutes
= 7040 feet
Since each car is 50 feet long, we can determine the number of cars in the long freight train by dividing the total distance traveled by the length of each car.
Number of cars = Total distance / Length of each car
= 7040 feet / 50 feet
= 140 cars
Therefore, there are 140 cars in the long freight train.
First, we need to convert the speed from miles per hour to feet per minute since the given length of each car is in feet.
1 mile = 5280 feet (12 inches/foot * 5280 feet/mile)
Therefore, the speed is 40 miles/hour * 5280 feet/mile = 211,200 feet/hour.
Since there are 60 minutes in an hour, the speed in feet per minute is:
211,200 feet/hour ÷ 60 minutes/hour = 3,520 feet/minute.
Next, we need to calculate the distance that the train travels in 2 minutes at a speed of 3,520 feet/minute:
Distance = Speed * Time = 3,520 feet/minute * 2 minutes = 7,040 feet.
Now, we can determine the number of cars in the train by dividing the distance covered by the length of each car:
Number of cars = Distance ÷ Length of each car = 7,040 feet ÷ 50 feet per car = 140.
Therefore, there are 140 cars in the long freight train.
