Question

Katya is traveling by train to visit her relatives in another state. The equation y=60x+20 represents the total distance she is from her home (y) after x hours of traveling on the train

Answer 1

Explanation:

Step one:

Given

The expression for Katya's distance away from home is given by the expression

`y=60x+20`

y represents her total distance away from home

x= represent the time of travel in hours

Step two:

60 represents the rate at which the train is traveling in km per hour

20 represents the initial distance from home

we predict her distance away at a given time

say 4 hours, that is x=4hours

substituting in the expression

y=60x+20

y=60(4)+20

y=240+20

y=260km
