Answer:
The distance between the astronomers and the moon was meters.
Step-by-step explanation:
We have that the speed is the distance divided by the time, so:
In this problem, we have that:
The reflected laser beam was observed by the astronomers 2.52 s after the laser pulse was sent. This means that .
If the speed of light is 3.00 times 10^8 m/s, what was the distance between the astronomers and the moon?
We have that m/s.
We have to find d. So:
The distance between the astronomers and the moon was meters.
Answer:
Distance: 25 miles
Step-by-step explanation:
we have distances between cities as follows:
From Portland to Tacoma: 120 miles
from Portland to Seattle: 145 miles
120+x=145 ⇒ x = 145 - 120 = 25 miles
from Tacoma to Seattle : 25 miles (according graph)
In the figure we have three parallel lines cut by two transversals
The theorem stares:
If two or more parallel lines are cut by two transversals, then they divide the transversals proportionally.
Applying this theorem we have:
To solve for x we cross multiply
6x=20
Dividing both sides by 6 we have:
The second option x= is the right answer
