(a) The proportion that can be used to find t is:
350/40 = 70/t
(b) To find the time it takes the satellite to travel 70 kilometers, set up the equation from part (a):
350/40 = 70/t
Cross multiply:
350 * t = 40 * 70
350t = 2800
Divide both sides by 350:
t = 2800/350
t = 8
Therefore, it takes the satellite 8 seconds to travel 70 kilometers.
Suppose a satellite orbiting Earth travels 350 kilometers in 40 seconds. At this rate, how much time does it take it to travel 70 kilometers?
(a) Let t be the unknown amount of time it takes the satellite (in seconds). Using the values below, create a proportion that can be used to find t.
Values: t , 350 , 40 , 70
(b) Use the proportion from part (a) to find the time it takes the satellite to travel 70 kilometers. Do not round any computations.

For a) how can that be in a fraction?
I apologize for the mistake. You are correct, the proportion should be set up using fractions.
The correct proportion is:
350/40 = 70/t
To find the time it takes the satellite to travel 70 kilometers, cross multiply:
350 * t = 70 * 40
350t = 2800
Divide both sides by 350:
t = 2800/350
t = 8
Therefore, it takes the satellite 8 seconds to travel 70 kilometers.
