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.

First, let's take a look at our problem.
"The speed of a ship is given by D3, where D is the distance the ship travels in 3 hours. If the ship travels 48 miles in 3 hours, what is the speed of the ship?"
To solve for this, we need to understand the formula for speed.
The formula for speed is:
Speed =
Now that we have our formula, let's define our variables.
So, we have our distance, 48 miles, and our time, 3 hours.
Let's plug in these numbers to the formula.
Speed =
Simplify the fraction to get the speed.
= 16.
Your final equation is:
Speed = 16.
Our final answer is 16 mph.
I hope this helps!
