<h3>
Answer: 6.93</h3>
Work Shown:
Use the pythagorean theorem to find x
a^2 + b^2 = c^2
x^2 + 11^2 = 13^2
x^2 + 121 = 169
x^2 = 169 - 121
x^2 = 48
x = sqrt(48)
x = 6.92820323027551
x = 6.93
Answer:
3.5 hours
Step-by-step explanation:
Speed of train X=30 mph
Speed of train Y=40 mph
Relative speed When the two trains travelling in same direction
Relative speed=40-30=10 mph
Total distance =25+10=35 miles
We have to find the time when train Y is 10 miles ahead of train X.
We know that
Time=![\frac{Distance}{Relative\;speed}](https://tex.z-dn.net/?f=%5Cfrac%7BDistance%7D%7BRelative%5C%3Bspeed%7D)
Using the formula
Then, we get
Time=![\frac{35}{10}=3.5 hours](https://tex.z-dn.net/?f=%5Cfrac%7B35%7D%7B10%7D%3D3.5%20hours)
Hence, it will be 3.5 hours until train Y is 10 miles ahead of train X.
