A communication satellite orbiting the earth travels about 18 miles every 4 seconds. How far will the satellite travel in 60 seconds?
a. 270 miles
b. 72 miles
c. 360 miles
d. 248 miles
60s * 18mi/4s = 60*18/4 = 270 mi
To find out how far the satellite will travel in 60 seconds, you need to calculate the distance it travels in 1 second and then multiply it by 60.
Given that the satellite travels 18 miles every 4 seconds, you can calculate its speed in 1 second by dividing 18 miles by 4 seconds:
18 miles / 4 seconds = 4.5 miles/second
Now, you can find how far the satellite will travel in 60 seconds by multiplying its speed by the duration:
4.5 miles/second * 60 seconds = 270 miles
Therefore, the satellite will travel 270 miles in 60 seconds.
So, the correct answer is:
a. 270 miles
To find the distance the communication satellite travels in 60 seconds, we can first find the distance it travels in 1 second and then multiply it by 60.
We know that the communication satellite travels 18 miles every 4 seconds. So, to find the distance it travels in 1 second, we need to divide 18 miles by 4 seconds.
18 miles ÷ 4 seconds = 4.5 miles
Therefore, the satellite travels 4.5 miles in 1 second.
To find the distance it travels in 60 seconds, we multiply 4.5 miles by 60.
4.5 miles × 60 seconds = 270 miles
So, the satellite will travel 270 miles in 60 seconds.
Therefore, the correct answer is a. 270 miles.
