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
Answer:
Step-by-step explanation:
..
Basically you get the volume first:
10 times 10 times 50
Which is 5,000
And we're given the cans volume already:
9.42
So what we do now is divided the area by the cans for our answer:
5,000/9.42
Which is 530.785563
So Sean can stack 530 cans of beans in his shelf.
(when rounding is is 531 cans)
