Lilly takes a train each day to work that averages 35 miles per hour. On her way home, her train ride follows the same path and
Klio2033 [76]

Answer: 2.5=\frac{n}{35}+\frac{n}{45}


Step-by-step explanation:

1. To find the equation asked, you must add the times:

t_{total}=t_1+t_2

Where t_1 is the time takes Lilly in her path to work and t_2  is the time takes Lilly in her path to home.

2. You must use the following formula of speed and solve for the time

V=\frac{n}{t}

Where n is the distance, V is the speed and t is the time.

3. You know that Lilly takes a train each day to work that averages 35 miles per hour, then, you can write the following expression:

35=\frac{n}{t_1}\\t_1=\frac{n}{35}

4. And her train ride follows the same path at 45 miles per hour:

 45=\frac{n}{t_2}\\t_2=\frac{n}{45}

5. Then, you obtain the following equation:

2.5=\frac{n}{35}+\frac{n}{45}

For negative numbers, as the numbers continue to increase the less the value will become.
