0,1.5

Step-by-step explanation:

y = 510 - 60x

We want to find the domain or the x values where x represents the time

We need to determine the possible values for x

Y cannot be greater than 510 or less than 0. 510 means they have not started the trip, and 0 means they have arrived

510 = 510 - 60x

Subtract 510 from each side

510-510 = 60x

0 = 60x

The smallest value of x can be 0

0 = 510 - 60x

Subtract 510 from each side

-510 = 510-510-60x

-510=-60x

Divide by - 60

-510/-60 = - 60x/-60

8.5 = x

The maximum value of x is 8.5 hours

So x must be between 0 and 8.5 inclusive.
