After 1 hour they are only 32 miles apart. Then after 12 minutes they meet
The children's ticket is $6 and an adults ticket is $8.
Set up two equations, 2A+C=22 and A+3C=26.
Rearrange the second equation to A=26-3C. Now plug this in to the first equation so you get 2(26-3C)+C=22 and solve
To answer the question above, we will have to use some calculus approach to this problem.
<span>volume of sphere = (4/3)(pi)(radius^3) = (4/3)(pi)(9^3) = 972pi </span>
<span>mass = (density)(volume) = (972pi)(1,000) = 972,000pi </span>
<span>force = (mass)(acceleration or gravity here) = (972,000pi)(9.8) = 9,525,600pi </span>
<span>work = (force)(distance) = (9,525,600pi)(4.5) = 42,865,200pi J
