Wendy took a trip from one city to another, a distance of 230 mi. She traveled part of the way by bus, which arrived at the train station just in time for Wendy to complete her journey by train. The bus averaged 40 mi/h, and the train averaged 90 mi/h. The entire trip took 4 and 1/2 h. How long did Wendy spend on the train?

really your just stupid if you don't know this

step-by-step explanation:

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .

brainliest is always apprectiated

the answer to this in exact form is 4/35 but in decimal form its 0.1142857

hope this if needed hmu
