Atrain travels 240 miles in 5 hours. at this rate, how far could the train go in 13 hours? what is the rate of speed of the train

We can set up a proportion with the information:

=

where x = the miles the train travels in 13 hours.

Now solve for x; multiply the numerator of the first fraction by the denominator of the second fraction and vice versa, and set them equal to each other:

240 · 13 = 5 · x

3120 = 5x

Finally, use the Division Property of Equality to divide both sides by 5 and find the value of x:

624 = x

Therefore, the train travels 624 miles in 13 hours.

Hope this helps! :)

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
