1 answer:
Answer:
or 50 miles per hour
Step-by-step explanation:
Let the speed of a train be x miles per hour
Total distance is given to be traveled by train= 250 miles
Total time taken to cover the distance= 5 hours
We have to find the expression to find the speed of a train
As we know Speed =
Hence, Speed of a train = miles per hour
Speed of a train = 50 miles per hour.
Hence, the correct answer is or 50 miles per hour

Step-by-step explanation:
1) Find the Greatest Common Factor (GCF).
1 - What is the largest number that divides evenly into and
?
It is
2 - What is the highest degree of that divides evenly into
and
?
It is 1, since is not in every term.
3 - Multiplying the results above,
The GCF is 4.
2) Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
3) Simplify each term in parentheses.
4) Factor out common terms in the first two terms, then in the last two terms.
5) Factor out the common term .
