Answer: after 1.8 hours, they would be 306 miles apart.
Step-by-step explanation:
Let t represent the time it will take for the two trains to be 306 miles apart. It means that after t hour, both trains would have covered a total of 306 miles.
Distance = speed × time
The eastbound train travels at 75 miles per hour. It means that the distance travelled by the eastbound train after t hours is 75t miles.
The westbound train travels at 95 miles per hour. It means that the distance travelled by the westbound train after t hours is 95t miles.
Since the total distance covered after t hours is 306 miles, it means that
75t + 95t = 306
170t = 306
t = 306/170
t = 1.8
Answer:
She bought 10 apples and 10 bananas
Step-by-step explanation:10 apples - $1.50 each x 10 apples = $15.00
10 bananas - $1.25 each x 10 bananas = $12.50
15.00+12.50=$27.50
x+y=28.00
1.50x+1.25y=28
Step-by-step explanation:
The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
