Let n = the hours elapsed when the two trains are 660 miles apart.
Let the first train travel east and the second train travel west.
The distance traveled by the first train is
x = (50 mi/h)*(n h) = 50n mi
The distance traveled by the second train is
y = (60 mi/h)*(n h) = 60n h
The distance between the two trains after n hours is
x + y = 50 n + 60n = 110n mi
Because this distance is 660 miles, therefore
110n = 660
n = 6 hours
Answer: 6 hours
I hope this helps. Sorry it took so long
Pie charts are used to illustrate data in proportions and percentages
The height of the bar for "Drama" is 70
<h3>How to determine the height of the bar</h3>
The number of results is given as:
n = 500
The pie chart is not given.
So, we solve this question using an assumed value for the proportion (p) of "Drama" movie genre
Assume that the proportion is 14%, then the height of the bar would be:
Height= 14% * 500
Multiply
Height= 70
Hence, the height of the bar for "Drama" is 70
