The Carter family drove 285 miles in 4 hours and 45 minutes. The Hernandez family drove 294 miles in 5 hours and 15 minutes.

See the analysis below

Step-by-step explanation:

Given data

The Carter family

Distance= 285 miles

Time= 4 hours 45 minutes.

Time= 4.75 hoursconverted time to hours

Speed= distance/time

Speed= 285/4.75

Speed= 60 miles per hour

The Hernandez family

Distance=294 miles

Time= 5 hours and 15 minutes.

Time= 5.25hoursconverted time to hours

Speed= distance/time

Speed= 294 / 5.25

Speed= 56 miles per hour

Hence the Carter family  is travelling faster at 60 miles per hour

0 is its x and y coordinate

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
