First, we are going to want to plug in the values we are given. In this case, we will end up with the equation:
From here, we can solve the equation to find :
- Apply the commutative property to rearrange the terms on the right-side of the equation to make the distributive property more apparent
- Apply the distributive property
- Subtract 8 from both sides of the equation
- Divide both sides of the equation by -2
We have found that c = 1.
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=
Using the formula
Then, we get
Time=
Hence, it will be 3.5 hours until train Y is 10 miles ahead of train X.
