The difference of the distances traveled by the comets for any given number of minutes is 25t.
Since the first comet travels at a speed of 30,000 miles per hour, the distance it travels in t minutes is d = 30000 mph × 1 h/60 min × t = 500t miles.
Also, the second comet travels at a speed of 28,500 miles per hour, the distance it travels in t minutes is d' = 28,500 mph × 1 h/60 min × t = 475t miles.
So, the difference in the distances traveled by the comets D = d - d'
= 500t - 475t
= 25t
So, the difference of the distances traveled by the comets for any given number of minutes is 25t.

Answer:
Average speed of train = 4x/3 miles per hour
Step-by-step explanation:
A train travels x miles in 3/4 hours
Let's find the distance train travels in 1 hour.
i.e distance travel in one hour = x /(3/4)
or distance travel in one hour = 4x/3
So,
Average speed of train = distance / time
Average speed of train = ( 4x/3 / 1 )
Average speed of train = 4x/3 miles per hour
Answer:
<u>The perimeter = 29.105 units</u>
Step-by-step explanation:
The rest of the question is the attached figure.
The perimeter of the figure shown = AB + BC + CD + DE + EF + FG + GA
AB = 5 units
BC = √(1² + 4²) = √17 ≈ 4.123 units
CD = √(4² + 4²) = √32 ≈ 5.657 units
DE = √(1² + 3²) = √10 ≈ 3.162 units
EF = 3 units
FG = √(1² + 3²) = √10 ≈ 3.162 units
GA = 5 units
So, The perimeter = 5 + 4.123 + 5.657 + 3.162 + 3 + 3.162 + 5 = 29.105 units
<u>So, The perimeter = 29.105 units</u>
