Question
A train travel at 100 mile per hour for 2.5 hours and the travels at 140 miles per hour for 1.5 hours. How far did the train travel in entire 4 hours?A)730 milesB)630milesC)460milesD)None of these.
Solution
To solve this problem, we need to calculate the distance traveled at each speed and then add them together.
-
First, we calculate the distance traveled at 100 miles per hour for 2.5 hours. Distance is speed multiplied by time, so 100 miles/hour * 2.5 hours = 250 miles.
-
Next, we calculate the distance traveled at 140 miles per hour for 1.5 hours. Again, distance is speed multiplied by time, so 140 miles/hour * 1.5 hours = 210 miles.
-
Finally, we add the two distances together to get the total distance traveled. 250 miles + 210 miles = 460 miles.
So, the train traveled 460 miles in 4 hours. The answer is C) 460 miles.
