The rate that train 1 is going plus the distance:

35x+52.5

The rate that train 2 is going plus the distance:

56x+0

X=number of hours

Solve for X to find where the 2 trains have gone the same distance:

35x+52.5=56x
52.5=21x
2.5=x

The express train will overtake the local train 2 and a half hours after it leaves

H(j + i) - k5 + h<br> when h = 3, i = 4, j = 2, and k = 1<br> pls put how you did it
VikaD [51]

Answer:

16

Step-by-step explanation:

First you want to plug in all the numbers where the letters are

h ( j + i )- k(5) + h

3 ( 2 + 4 )- 1(5) + 3

After this step you will have to distribute the 3 outside the parenthesis. Which you do by multiplying everything in side the parenthesis by the outside number which is three.

6 + 12 - 1(5) + 3

Then you just follow PEMDAS to solve for the rest

6 + 12 - 5 + 3

18 - 5 + 3

13 + 3
