Answer:
4 hours
Step-by-step explanation:
The general formula for distance, rate and time is:
d = rt, where distance is the product of rate multiplied by time
Given that one train is moving at a rate of 70 mph and one is moving at a rate of 62 mph in the opposite direction, the combined distance over time is equal to 528 miles. Using the variable 't' for time:
70t + 62t = 528
Combine like terms: 132t = 528
Divide both sides by 132: 132t/132 = 528/132 or t = 4 hours
Answer:
153 yards..
Step-by-step explanation:
umm due to the pythagorean theorem it would be 45^2+24^2=c^2
= 2025+576=c^2
= 2601=c^2
= square root of 2601 is 51
since there are 3 cables it would be 51*3=153
Let m and j be the current ages of Matthew and Jenny, respectively.
Now, Matthew is 3 times as old as Jenny, so the variables are in the following relation:
![m=3j](https://tex.z-dn.net/?f=m%3D3j)
In 7 years, both of them will be 7 years older, i.e. their ages will be m+7 and j+7, and Matthew will be twice as old:
![m+7=2(j+7)](https://tex.z-dn.net/?f=m%2B7%3D2%28j%2B7%29)
Now, remembering that m=3j, we can rewrite the second equation as
![3j+7=2j+14 \iff j = 7](https://tex.z-dn.net/?f=3j%2B7%3D2j%2B14%20%5Ciff%20j%20%3D%207)
So, Jenny is 7 and Matthew is 21 (he's 3 times older).
In fact, in 7 years, they will be 14 and 28, and Matthew will be twice as old.
