Junior wanted to ride a roller coaster at Six Flags. The sign says you have to be 48 inches to ride the roller coaster. The roller coaster can travel 540 feet in 6 seconds.
1. What is the unit rate of the number of feet per second the roller coaster would move?
HELP

90 feet per second.

Step-by-step explanation:

If it moves 540 feet in 6 seconds, than it moves 540/6=90feet per second.

Not sure what the height requirement has to do with this problem or what 'unit rate' is specifically referring to so this may not be the answer you're looking for but I hope this helped anyway!

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
