Okay, this is a written proof so what you have to do is list the steps. I am going to try my best to solve this problem...
Answer: The speed of car B is 6.44 m/s
Step-by-step explanation:
Let's define:
Sa = Speed of car A.
Sb = Speed of car B.
I assume that at t = 0s, the position of car A is 0m (then at t = 0s, the position of car B is 174m)
Then we can write the positions of each car as:
Pa(t) = Sa*t
Pb(t) = Sb*t + 174m.
We also know that Sa = 2*Sb.
And we know that at t= 27s, car A passes car B.
Then at t = 27s, the positions of both cars must be the same:
Pa(27s) = Pb(27s)
Sa*27s = Sb*27s + 174m.
Now we can replace Sa by 2*Sb (from the above equation)
2*Sb*27s = Sb*27s + 174m
Now we can solve this for Sb.
2*Sb*27s - Sb*27s = 174m
Sb*27s = 174m
Sb = 174m/27s = 6.44m/s.
The speed of car B is 6.44 m/s
Based on the distances between the cities, the answer to this question will be<u> 185 miles. </u>
Distance between Dallas and Omaha - 644 miles
Distance between Chicago and Omaha - 459 miles
<h3 /><h3>How much closer is Chicago to Omaha than Dallas?</h3>
= Distance between Dallas and Omaha - Distance between Chicago and Omaha
= 644 - 459
= 185 miles
In conclusion, it is 185 miles which is <u>One Hundred and Eighty Five miles. </u>
