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.
That is impossible to answer because this is an expression. you can only solve for x in equations
