Question

A train runs (x² + 2x² -15) in (x² - 3 ) . Find the speed of the train in km/hour​

Answer 1

Step-by-step explanation:

• $distance = {x}^{2} + 2 {x}^{2} - 15$
• $time = {x}^{2} - 3$
• $speed \: = \frac{distance}{time}$
• $= \frac{ {x}^{2} + 2 {x}^{2} - 15 }{ {x}^{2} - 3}$
• $= (2 {x}^{2} - 5)km \: per \: hour$

Answer 2

Answer:

Here's your answer.

Step-by-step explanation:

speed = distance/ time

speed = (x² + 2x² -15) / (x² - 3 )

speed = 3 - 6 / x^2 -3

Therefore speed of train = 3 - 6/x^2-3
