A radio signal travels at
3.00 ⋅ 10^8 meters per second. How many seconds will it take for a radio signal to travel from a satellite to the surface of Earth if the satellite is orbiting at a height of 3.54 ⋅ 10^7 meters? Show your work.
This is my question in Algebra and was wondering how do I do it so I multiply them, divide them, subtracting, or adding?
yeas bro
just remember your units.
distance = speed * time, so
time = distance/speed
So it would be 3.00*10^7 * 3.54*10^7? To get the answer?
Sorry about that:( So instead of multiplying I divide?
To solve this problem, you need to use the formula:
Time = Distance / Speed
In this case, the distance is the height of the satellite from the surface of the Earth, which is 3.54 ⋅ 10^7 meters. The speed is the speed of the radio signal, which is given as 3.00 ⋅ 10^8 meters per second.
Now, substitute the values into the formula:
Time = (3.54 ⋅ 10^7 meters) / (3.00 ⋅ 10^8 meters per second)
To divide numbers written in scientific notation, divide their coefficients and subtract their exponents:
Time = 3.54 / 3.00 ⋅ 10^7 / 10^8
Simplifying this, we get:
Time = 1.18 ⋅ 10^(-1) seconds
So, it will take approximately 0.118 seconds for the radio signal to travel from the satellite to the surface of Earth.
excuse me? You want the time, right? They already gave you the distance
time(s) = distance (m) ÷ speed (m/s)
If you include your units, you will never be confused on what gets divided or multiplied. Your final answer must be in the correct units.
You need to
(a) read the question carefully
(b) pay attention when help is given, not grab the first thing you see.
