Answer:
195 ft.
Step-by-step explanation:
I don't have an actual explanation because I simply guessed based on the dimensions and what made the most sense and I got it right. If someone has an explanation as to why it is 195 ft please lmk. Other than that, 195 ft is the correct answer.
Answer: the rate of speed for train A is 66 miles per hour.
Step-by-step explanation:
Let x represent the speed of train B.
2 trains leave the station at the same time. Train A is traveling 16 miles per hour slower than train B. This means that the speed of train A would be x - 16 miles per hour.
The two trains are 720 miles apart after 4 hours. It means that both trains traveled a total distance of 720 miles in 4 hours.
Distance = speed × time
Distance travelled by train A after 4 hours is
4(x - 16) = 4x - 64
Distance travelled by train B after 4 hours is
4 × x = 4x
Since the total distance travelled by both trains is 720 miles, then
4x - 64 + 4x = 720
8x = 720 - 64 = 656
x = 656/8 = 82 miles per hour
The speed of train A would be
82 - 16 = 66 miles per hour.

Answer:
y - 3 = -1/2(x-1)
Step-by-step explanation:
Given the coordinates (1, 3) and (5,1). The point slope form is expressed as;
y - y0 = m(x-x0)
m is the slope
(x0, y0) is the required point
Get the slope
m = 1-3/5-1
m = -2/4
m = -1/2
Using the point (1,3), substitute
y - 3 = -1/2(x-1)
2(y-3) = -(x-1)
Hence the required equation is y - 3 = -1/2(x-1)
