A train travels 250 miles at a constant speed (x), in miles per hour.

Enter an equation that can be used to find the speed of the train, if the time to travel 250 miles is 5 hours.

 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

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
