Riley's grandparents drive from city A to city B every spring. It takes them several days. Each day they use the expression 2+ distance over 54 to figure out how many hours they will be on the road. The first day they were on the road for 7 hours. How far did they travel on the first day?

9514 1404 393

  270 miles

Step-by-step explanation:

For h hours of driving the distance d is covered:

  h = 2 +d/54

Solving for d, we find the distance covered in h hours is ...

  d = 54(h -2)

In 7 hours, the distance they traveled is ...

  d = 54(7 -2) = 270 . . . miles

They traveled 270 miles on the first day.

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
