Remark
the question depends on d= r * t
d = the distance in miles.
r = the rate of travel in miles per hour
t = the time in hours.
Step One
Rearrange the formula so you are solving for the rate.
d = r * t Divide by t
4 5/6 = (4*6 + 5)/6 = 29/6
r = d / t
Step Two
Substitute into the equation.
Step Three
Turn the bottom fraction upside down. Multiply these two together.
r = 
r = 29/4 miles hour.
Step Four
Solve for d when t = 1 hour.
d = ??
r = 29/4 miles / hour
t = 1 hour.
d = 29/4 * 1
d = 29/4 miles
That's as simple as you can get it unless you want 7 1/4 miles or 7.25 miles
Answer:
Since zero is on the origin (0,0) a 90 degree rotation will intercept the origin no matter what so, it can't be parallel.

Answer:
5817 Newtons.
Step-by-step explanation:
Total mass of the cage + the miners = 700 Kg which is a downward force of 700g N.
The net downward force = 700g - T where T is the tension (force) in the cable. The g = acceleration due to gravity = 9.81 m s-2.
We calculate the acceleration of the cage by using an equation of motion:
Distance = ut + 1/2 a t^2 where u = initial velocity , t = time and a = acceleration:
75 = 0(t) + 1/2 a (10^2)
50a = 75
a = 1.5 m s-2.
So using Newtons second law of motion
Force = mass * acceleration:
700*9.81 - T = 700 * 1.5
T = 700 * 9.81 - 700*1.5
= 5817 N.
